Check client connection to SQL Server 2008 Express [duplicate] - sql-server

I just installed SQL Server 2008 Express on my Vista SP1 machine. I previously had 2005 on here and used it just fine with the old SQL Server Management Studio Express. I was able to connect with no problems to my PC-NAME\SQLEXPRESS instance (no, PC-NAME is not my computer name ;-).
I uninstalled 2005 and SQL Server Management Studio Express. I then installed SQL Server 2008 Express on my machine and elected to have it install SQL Server Management Studio Basic.
Now, when I try to connect to PC-NAME\SQLEXPRESS (with Windows Authentication, like I always did), I get the following message:
Cannot connect to PC-NAME\SQLEXPRESS.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)

When I installed SQL Server 2008, I had it use SQLEXPRESS as the local instance name. As far as I can tell, through SQL Server Configuration Manager, SQL Server is configured to allow remote connections.
When I went to the help link it mentions, the help page suggests the following:
Make sure that the SQL Server Browser service is started on the server.
Use the SQL Server Surface Area Configuration tool to enable SQL Server to accept remote connections. For more information about the SQL Server Surface Area Configuration Tool, see Surface Area Configuration for Services and Connections.
Well, as far as I can tell, there is no SQL Server Browser service on my system (looked in MMC for one, couldn't find one).
And the SQL Server Surface Area Configuration tool doesn't exist in SQL Server 2008. So good job there with your help documentation, Microsoft ;-).
I'm at a loss for what to do right now. I had a lot of work I was hoping to get done today after upgrading to 2008 (the person I'm working with got it up and running with no problem and told me it would be easy - he's also far better with database stuff that I am). Does anyone have any idea what might be wrong? I'd really appreciate it. If I can't get this working in a few hours, I'm going back to SQL Server 2005 (if that will even work, gah...).
Edit: I have tried turning Windows Firewall off, and that did not help. Also, I noticed that I do not have a "Data" directory under my SQL Server 2008 install directory tree - could I have possibly set something up wrong when I installed it?

Please check the ServerName which you provided. It should match with the below shown Name in the UserName textbox, and that name should followed with \SQLEXPRESS:

Start your Local SQL Server Service
Start SQL Config Manager: Click Start -> Microsoft SQL Server 2008 R2 -> SQL Server
Configuration Manager
Start SQL Services: Set the SQL Server (SQLEXPRESS) and SQL Server Browser services to automatic
start mode. Right-click each service -> Properties -> Go into the Service Tab
This will ensure they start up again if you restart your computer. Please check to ensure the state is "Running" for both services.
Login and authenticate with your Local SQL Server
Now open up SQL Server Management Studio and click "Connect to Object
Explorer" and select Server Name:
[Your PC name]\SQLEXPRESS
Example: 8540P-KL\SQLEXPRESS or (localhost)\SQLEXPRESS
To find your PC name: Right click My Computer -> Properties ->
Computer Name tab
Alternative: Login using windows authentication: Using the user name [Your
Domain]/[Your User Name]
Setup User Account
Create a new Login acct: In SQL Mgmt Studio -> Expand your local Server -> Security -> Right
click on Logins -> New Login
Set Password settings on New User Account: Uncheck Enforce password policy, password expiration and user must
change pw(Since this is local) Default database -> Your Database
Grant roles to New User Account: User Mapping Page -> Map to your db and grant db_owner role Status
Page -> Grant Permission to connect and Enable Login
Setup Access Permissions/Settings for User
Enable all auth modes: Right click your Local Server -> Properties -> Security Tab -> Enable
SQL Server and Windows Authentication Mode
Enable TCP/IP: Open SQL Server Configuration Manager -> SQL Server Network
Configuration -> Protocols for SQLEXPRESS -> Enable TCP/IP
Restart SQL Server Service: You will have to restart the SQL Server(SQLEXPRESS) after enabling TCP/IP
Database Properties File for Spring Project
database.url=jdbc:jtds:sqlserver://[local PC Computer
name];instance=SQLEXPRESS;DatabaseName=[db name];
database.username=[Your user name] database.password=[Your password]

Setting up a Local Instance of SQL Server 2008 Blog Post:

I used (LocalDB)\MSSQLLocalDB as the server name, I was then able to see all the local databases.

Haha, oh boy, I figured it out. Somehow, someway, I did not install the Database Engine when I installed SQL Server 2008. I have no idea how I missed that, but that's what happened.

I know this question is old, but in case it helps anyone make sure the SQL Server Browser is running in the Services MSC. I installed SQL Server Express 2008 R2 and the SQL Server Browser Service was set to Disabled.
Start->Run->Services.msc
Find "SQL Server Browser"->Right Click->Properties
Set Startup Type to Automatic->Click Apply
Retry your connection.

I've just solved a problem related to this which may help other people.
Initially when loading up MSSMSE it had the server as PC_NAME\SQLEXPRESS and when I tried to connect it gave me Error: 26 - Error Locating Server/Instance Specified, so I went into SQL Server Configuration Manager to check if my SQL Server Browser and SQL Server services were running and set to automatic, only to find that instead of saying SQL Server (SQLEXPRESS) it says SQL Server(MSSQLSERVER).
I then tried connecting to PC-NAME\MSSQLSERVER and this time got SQL Network Interfaces, error: 25 - Connection string is not valid) (MicrosoftSQL Server, Error: 87) The parameter is incorrect so I googled this error and found that somebody had suggested that instead of using PC-NAME\MSSQLSERVER just use PC-NAME as the Server Name at the server connection interface, and this seems to work.
There's a link here http://learningsqlserver.wordpress.com/2011/01/21/what-version-of-sql-server-do-i-have/ which explains that MSSQLSERVER is the default instance and can be connected to by using just your hostname.
I think this may have arisen because I've had SQL Server 2008 installed at some point in the past.

Under Configuration Manager and Network Configuration and Protocols for your instance is TCP/IP Enabled? That could be the problem.

var.connectionstring = "server=localhost; database=dbname; integrated security=yes"
or
var.connectionstring = "server=localhost; database=dbname; login=yourlogin; pwd=yourpass"

For me, I was only able to get it to work by using "." in the server name field; was banging away for awhile trying different combos of the user name and server name. Note that during install of the server (ie this file: SQLEXPR_x64_ENU.exe) i checked default instance which defaults the name to MSSQLSERVER; the above high voted answers might be best used for separate named (ie when you need more than 1) server instances.
both of these videos helped me out:
use dot for server name: https://www.youtube.com/watch?v=DLrxFXXeLFk
general setup: https://www.youtube.com/watch?v=vng0P8Gfx2g

One of the first things that you should check is that the SQL Server (MSSQLSERVER) is started. You can go to the Services Console (services.msc) and look for SQL Server (MSSQLSERVER) to see that it is started. If not, then start the service.
You could also do this through an elevated command prompt by typing net start mssqlserver.

For me it was a windows firewall issue. Allow incoming connections. Opening port didn't work but allow programs did.

SQL Server 2019 support in DataGrip (can't connect to an instance)

I don't seem to be able to connect to a locally installed SQL Server 2019 instance using DataGrip (2019.3).
No matter which auth I use (domain or SQL), I get the following error:
"The specified database user/password combination is rejected: [08S01] The server SQL19 is not configured to listen with TCP/IP"
URL I'm connecting to is jdbc:sqlserver://localhost\SQL19.
If instead of "SQL19" part I use SQL Server 2016 instance name, it works fine,
so I'm assuming I'm configuring the connection correctly, unless there's some tweaks I need for SQL 2019?
I can connect to a 2019 instance from SSMS and applications, it's available via TCP/IP etc.
Answering my own question with some details (#moscas answer is correct, but I feel details may still be useful for somebody).
TCP/IP seems to be disabled by default in SQL Server 2019, and SQL Configuration Manager turned out to be not easy to find: it doesn't show up when you do regular search in "Start" menu and it doesn't exist under SQL Server's folder in the menu (wtf, Microsoft?).
You need to go Computer Management (this does show up in search) -> Services and Application -> SQL Server Configuration Manager -> SQL Server Network Configuration, choose your instance and enable TCP/IP.
Datagrip starts to work then.
As far as I know, SSMS does not require TCP/IP, that's why it works. For DataGrip, you need to turn it on.
Perhaps this doc will help: https://www.jetbrains.com/help/datagrip/db-tutorial-connecting-to-ms-sql-server.html
In additional to enable TCP/IP in SQL Server Configuration Manager. I also had to enable the Sql Browser service under Sql Service Service.

Why can't I connect to my local SQL Server database instance?

I installed SQL Server 2008 (not express) on my PC, but when tried to connect with SSMS, got this message:
A network-related or instance specific error occured while established
a connection to SQL Server. The server was not found or was not
accessible. Verify that the instance name is correct and that SQL
Server is configured to allow remote connections.(provider: Named
Pipes Provider, error: 40- Could not open a connection to SQL Server)
(Misrosoft SQL Server, Error 2)
My connection dialog box to SSMS is:
Server type: Database Engine.
Server name: (local)
Authentication: Windows
What should I check? Where to start troubleshooting?
GO TO >> Run Command (Ctrl + r )
Type -- services.msc
go to SQL SERVER >> Right Click >> Click Start
Again Restart SQL SERVER Studio
Here are some troubleshooting tips that you can do:
Try to run your SSMS as admin
Make sure that you are using the correct server name and instance
Check if your sql server service is running by going to run -> services.msc -> Check SQL Server(Instance Name) service if it is running
Error 40 has many reasons, some of them are related to network configurations which are out of scope in your question. Other reasons which may cause this error and has possibility in your question are as follow:
Make sure that SQL SERVER(XXX) service is running by visiting sql server configuration manager section
Make sure that SQL Browser service is running by visiting sql server configuration manager section
Make sure you are using the correct instance name

If your server is Local. Try to login with server name . or (local).
If you are still not able to login, check Check SQL Server Configuration Manager (Start>All Programs>MS SQL Server>Configuration Tools>Configuration Manager)

SQL Server 2012 SSDT "The project could not be deployed to .... A connection cannot be made ...."

I'm a newbie to SQL Server 2012. Here is my condition.
I have a running SQL Server 2012 Business Intelligence SP1. The problem is I cannot deploy a project to my SSAS from another computer.
The error is:
The project could not be deployed to the 'DATABASE-SERVER\MSSQLSERVER' server because of the following connectivity problems : A connection cannot be made to redirector. Ensure that 'SQL Browser' service is running. To verify or update the name of the target server, right-click on the project in Solution Explorer, select Project Properties, click on the Deployment tab, and then enter the name of the server.
The following is the things that I've tried:
Check the target name on Project > Properties > Deployment > Target server.
Check the server service --> all SQL Server services are running.
The project can be deployed from server.
The connection to server is clear
I can connect to the Database Engine and Analysis Service from another computer from SQL Server Management Studio.
Please help me to fix this problem, I've been search for many days for this problem.
Thank you, sorry for my bad english.
Best regards, Stella.
I had the same problem, for me the solution was to explicitly specify login information on the Impersonation Information tab on the Data Source.
I know this is an old thread, but I had the same issue and I reckon more will run into this buzz saw.
My problem was that the remote installation of SSAS did not have an Inbound firewall rule for SSAS application; msmdsrv.exe.
Resolution:
Log on to the server running SSAS as Administrator
Launch Windows Firewall and advanced Security
Add Inbound Rule, give it a meaningful name like SQL Server - SSAS
Action: Allow the connection
On Program and Services Tab: For 'This Program' use Browse and identify msmdsrv.exe
For SQL Server 2014, it is by default here:
%ProgramFiles%\Microsoft SQL Server\MSAS12.SQLSVR14\OLAP\bin\msmdsrv.exe
(Very similar for 2012 and 2016, the numbers are different)
Click OK; You should see a green dot with check mark
Try your project again; It should connect, did for me.
NOTE: If this also work for you, consider going back to the Inbound Rule and consider adding connection restrictions for security reasons.
I solved mine by right clicking my data source (under Data Sources in Solution Explorer) → Edit in the General tab → In Connection Manager, do two things:
Change Server name from localhost to your computer name
Use SQL Server Authentication as Authentication, as opposed to Windows Authentication, and proceed to enter your user name and password (the "sa" password you use for SSMS).

Unable to connect to SQL Server instance remotely

I’m trying to access the SQL Server instance on my VPS from SQL Server Management Studio on my local machine. It’s not working (the error I’m getting is:
A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections.
I think this is because I need to configure the database engine to allow remote connections (correct me if I’m wrong!). So I’ve found this step-by-step guide to help me do that: http://www.linglom.com/2009/03/28/enable-remote-connection-on-sql-server-2008-express/ I’ve got to point 10 in the guide and I am now stuck! I don’t have SQL Server Management Studio installed on my VPS. Anyway, this has left me with two options:
Install SSMS
Find another way to do point 10 onwards in the guide without having SSMS installed
I tried installing SSMS on my VPS using the Web Platform Installer but it keeps failing. I don’t know why it’s failing because it doesn’t seem to give a reason why. Does anyone know how I could allow remote connections a different way?
The version of SQL Server installed on my VPS is SQL Server 2008 R2 Express.
Update:
I have tried to disable the firewall on both my laptop and VPS to see if it is a firewall issue. This made no difference to the error message.
Another Update:
Having now been able to install SSMS (I installed directly from the website rather than using the WPI), I have been able to check that the server is configured to allow remote connections (I went to SSMS, connected to the SQL Server instance, right-clicked on the connection, clicked Properties, went to the Connections tab. "Allow remote connections to this server" is already ticked).
SOLUTION
Thanks to everyone for helping me get to this solution! I've finally managed to get it to work! I followed Filip De Vos's advice and opened the ports in the Firewall on my VPS and then I received a different error message. This led me to investigate further and I found that I was using the wrong credentials to login! So I've set a password for the sa user and I've managed to login using that! Thanks again!
To enable mixed authentication you can change the following registry key:
HKLM\Software\Microsoft\Microsoft SQL Server\MSSQL.1\MSSQLServer\LoginMode
Update the value to 2 and restart the Sql Server service to allow mixed authentication. Note that MSSQL.1 might need to be updated to reflect the number of the SQL Server Instance you are attempting to change.
A reason for connection errors can be a virus scanner installed on the server which blocks sqlserver.exe.
Another reason can be that the SQL Server Browser service is not running. When this service is not running you cannot connect on named instances (when they are using dynamic ports).
It is also possible that Sql Server is not setup to listen to TCP connections and only allows named pipes.
In the Start Menu, open Programs > Microsoft SQL Server 2008 >
Configuration Tools > SQL Server Surface Area Configuration
In the Surface Area Configuration utility, click the link "SQL Server
Configuration Manager"
Expand "SQL Server Network Configuration" and
select Protocols.
Enable TCP/IP. If you need Named Pipes, then you can
enable them here as well.
Last but not least, the Windows firewall needs to allow connections to SQL Server
Add an exception for sqlserver.exe when you use the "Dynamic Port" system.
Otherwise you can put exceptions for the SQL Server ports (default port 1433)
Also add an exception for the SQL Server Browser. (udp port 1434)
More information:
How to: Configure a Windows Firewall for Database Engine Access
Server Connectivity How-to Topics (Database Engine)
As a last note, SqlLocalDB only supports named pipes, so you can not connect to it over the network.
In addition to configuring the SQL Server Browser service in Services.msc to Automatic, and starting the service, I had to enable TCP/IP in: SQL Server Configuration Manager | SQL Server Network Configuration | Protocols for [INSTANCE NAME] | TCP/IP
Launch SQL Server Configuration Manager on your VPS.
Take a look at the SQL Server Network Configuration. Make sure that TCP/IP is enabled.
Next look at SQL Server Services. Make sure that SQL Server Browser is running.
Restart the service for your instance of SQL Server.
Open the SQL Server Configuration Manager....
2.Check wheather TCP and UDP are running or not....
3.If not running , Please enable them and also check the SQL Server Browser is running or not.If not running turn it on.....
Next you have to check which ports TCP and UDP is using. You have to open those ports from your windows firewall.....
5.Click here to see the steps to open a specific port in windows firewall....
Now SQL Server is ready to access over LAN.......
If you wan to access it remotely (over internet) , you have to do another job that is 'Port Forwarding'. You have open the ports TCP and UDP is using in SQL Server on your router. Now the configuration of routers are different. If you give me the details of your router (i. e name of the company and version ) , I can show you the steps how to forward a specific port.
I had the same issue where my firewall was configured properly, TCP/IP was enabled in SQL Server Configuration Manager but I still could not access my SQL database from outside the computer hosting it. I found the solution was SQL Server Browser was disabled by default in Services (and no option was available to enable it in SQL Server Configuration Manager).
I enabled it by Control Panel > Administrative Tools > Services then double click on SQL Server Browser. In the General tab set the startup type to Automatic using the drop down list. Then go back into SQL Server Configuration Manager and check that the SQL Server Browser is enabled. Hope this helps.
Disable the firewall and try to connect.
If that works, then enable the firewall and
Windows Defender Firewall -> Advanced Settings -> Inbound Rules(Right Click) -> New Rules -> Port -> Allow Port 1433 (Public and Private) -> Add
Do the same for Outbound Rules.
Then Try again.
I recently upgraded from SQL 2008 R2 to SQL 2012 and had a similar issue. The problem was the firewall, but more specifically the firewall rule for SQL SERVER. The custom rule was pointed to the prior version of SQL Server. Try this, open Windows Firewall>Advanced setting. Find the SQL Server Rule (it may have a custom name). Right-Click and go to properties, then Programs and Services Tab. If Programs-This program is selected, you should browse for the proper version of sqlserver.exe.
If you have more than one Instances... Then make sure the PORT Numbers of all Instances are Unique and no one's PORT Number is 1433 except Default One...
Open SQL Server Configuration Manager.
Click SQL Server Services, on the right side choose the server you've created during installation (by default its state is stopped), click once on it and a play button should appear on the toolbar. Click on this play button, wait til its state turns to "Running". Now you're good.
Open SQL Server Management Studio; switch the "Server Type" to "Database Engine" and "Authentication" to "SQL Server Authentication". The default login is "sa", and the password is the password that you chose on creating the server. Now you're good to work.
In my case the problem was caused by the inconsistency between computer names. In system settings my computer was named with some long name, but apparently the name used for some certain communications was trimmed.
I changed the name in the settings to a shorter one and it worked.
I had built both a console app and a UWP app and my console connected fine, but not my UWP. After hours of banging my head against the desk - if it's a intranet server hosting the SQL database you must enable "Private Networks (Client & Server)". It's under Package.appxmanifest and the Capabilities tab.Screenshot

SQL Server 2008 Express Edition Connection Issue

I have VS 2008 Professional Edition. After the installation (which included SQL Server 2008), I decided to install SQL Server 2008 Express Edition with Advanced Tools (so I could get SQL Server Management Studio on it). So I uninstalled the SQL Express that came with VS 2008, and installed the standalone SQL Server Express 2008 version with advanced tools.
However, When I try to logon onto SQL Server Management Studio using:
.\SQLEXPRESS
as Server name and Windows Authentication as the authentication, I get the following message:
TITLE: Connect to Server
------------------------------
Cannot connect to .\SQLEXPRESS.

Any suggestions on how to get it to work? I have tried disabling Windows Firewall as well and still no luck.
I am using WIndows Vista and SQL Server 2008 Express SP1 Patch has also been applied recently.
FIX: For those interested:
I did not have any of the Instance Based installation installed (i.e. the Database engine). I Installed the instance based stuff and it fixed it!
Start your Local SQL Server Service
Start SQL Config Manager: Click Start -> Microsoft SQL Server 2008 R2 -> SQL Server
Configuration Manager
Start SQL Services: Set the SQL Server (SQLEXPRESS) and SQL Server Browser services to automatic
start mode. Right-click each service -> Properties -> Go into the Service Tab
This will ensure they start up again if you restart your computer. Please check to ensure the state is "Running" for both services.
Login and authenticate with your Local SQL Server
Now open up SQL Server Management Studio and click "Connect to Object
Explorer" and select Server Name:
[Your PC name]\SQLEXPRESS
Example: 8540P-KL\SQLEXPRESS or (localhost)\SQLEXPRESS
To find your PC name: Right click My Computer -> Properties ->
Computer Name tab
Alternative: Login using windows authentication: Using the user name [Your
Domain]/[Your User Name]
Setup User Account
Create a new Login acct: In SQL Mgmt Studio -> Expand your local Server -> Security -> Right
click on Logins -> New Login
Set Password settings on New User Account: Uncheck Enforce password policy, password expiration and user must
change pw(Since this is local) Default database -> Your Database
Grant roles to New User Account: User Mapping Page -> Map to your db and grant db_owner role Status
Page -> Grant Permission to connect and Enable Login
Setup Access Permissions/Settings for User
Enable all auth modes: Right click your Local Server -> Properties -> Security Tab -> Enable
SQL Server and Windows Authentication Mode
Enable TCP/IP: Open SQL Server Configuration Manager -> SQL Server Network
Configuration -> Protocols for SQLEXPRESS -> Enable TCP/IP
Restart SQL Server Service: You will have to restart the SQL Server(SQLEXPRESS) after enabling TCP/IP

Setting up a Local Instance of SQL Server 2008 Blog Post:
you can look for your instance name in SQL Server Configuration Manager. It is written between brackets after SQL Server service in the services list.
the . notation is correct and it's the same as (local)
Did you try using (local)\SQLEXPRESS in the name? I've not seen that . notation before.
Scott,
I had to enable SQL Server Browser in services once I did that I was able to connect on My recent install.
after that I only had to use the computer name as the server.
edit,
while researching further on finding sql server browser, noted that reporting services, service showed its instance as .\computer name.
try that as the server name.
edit again change to backslash been playing with linux recently :)
There is a possibility that you installed as Default instance. In this case, try connecting using (local) - just (local).
Then go to Programs/Microsoft SQL Server/Configuration Tools/SQL Server Configuration Manager. Go to SQL Server Network Configuration/Protocols for MSSQLSERVER and enable Named Pipes.
Have you tried looking at the SQL Server Surface Area Configuration? You might only have SQL Authentication setup and might need to enable Network and SQL Authentication.

I have an application that uses a connection string trough VSOT in Word 2007.
The application gave a connection error.
I allways install Sql server 2008 Express R2 in mixed mode so that i can use the build in sa with i password to connect.
I re-entered the password to be sure its correct. In a next step i opened:
‘Configuration manager’ in ‘Program files’ ‘Microsoft Sql Server 2008’ –->’ Configuration Tools’ and set all the other instances on the properties --> hide instance 'yes'
That solved the problem in my case.
