I built a window application in visual studio 2010. It is working fine at my computer.
if i have a pc that works with windows server 2008 and i install a sql server on it , how to make my application connect to database in the sql server that instaled in the server pc .
my pc connected to the server domain .
thanks
Assuming your application is already configured to use a Sql connection string, you'll just need to configure it for the Sql Server instance you're connecting to.
For example, if your database is called MyDatabase, and your windows server on your domain is called myserver.local, and you've installed Sql Express with the default SQLEXPRESS instance name, you could create your connection string (assuming ADO.NET) something like this:
Integrated Security=true;Initial Catalog=MyDatabase;Data Source=myserver.local\SQLEXPRESS
This configuration would be for Windows Authentication (Integrated Security=true): so your domain user accounts would need to be granted LOGIN rights on the server, and those Logins associated with USERS and ROLES in your database. If you wanted to use Sql Logins instead (generally requires extra configuration when setting up your Sql Server), there are different connection strings settings for specifying username and passwords. There are many options available for the connection strings as documented here: https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.connectionstring(v=vs.110).aspx. However, with Windows Authentication the only 3 you absolutely need are the ones shown above.
You can test connectivity to your Sql Server from your PC on the network using Sql Server Management Studio, which will enable you to verify the instance name and the authentication is working as expected if you can connect to the database.

I'm attempting to remotely connect to my SQL Express 2016 server through MS SQL on my local machine however am having extreme difficulties with the authentication.. Well I assume it is an authentication issue as when I attempt connect to connect to it I receive the error message:
The remote computer refused the network connection.
When connecting through the sqlcmd I am using Windows authentication and have no issue, however to connect to it remotely I need to use SQL authentication and have no memory of creating an account so am wondering if there's a default login and password?
I believe this is the issue however it is quite likely i'm doing something stupid so any assistance would be appreciated!
You can create an account that can be used to connect to that SQLExpress instance by using SQL Server Management Studio. Expand the database you wish to create a login for in the Object Explorer. Under the Security folder, you can create a new login by right clicking the Logins folder.
Also make sure that your machine has its firewall configured to allow remote connections, the server has remote connections enabled, and that you are allowing logins for Windows Auth and SQL Server Auth.
You can allow remote connections for a server by opening the SQL Server Configuration Manager. Under the SQL Server Network Confiuration Node, Select Protocols for MYSERVERNAME. Ensure that TCP/IP is enabled.
Here's a guide on setting up the firewall: https://technet.microsoft.com/en-us/library/ms175043(v=sql.110).aspx
You can enable SQL Server Authentication by right clicking your server name in the object explorer in SQL Server Management Studio and going to the Security tab. look for the "Server Authentication" option.
I want to connect my SQL server management studio which is running locally with a Azure SQL Server 2012 database
Now i have enable the sa account on the SQL server side and i also check the server name by running this query --
SELECT ##SERVERNAME
I got the output
MSRV01\SQLSERVER
Now from my local machine when i am trying to loginto that Azure SQL server like this --
It retun this error
Do any one have any idea what i am doing wrong here !
Unless your local machine is on the same domain (or even subnet) as the azure VM then accessing via machine hostname will never work.
If you are using an Azure hosted database (i.e. not a VM) then in your Management Portal, navigate to the database settings panel. At the top will be listed the Server name with a URL like xxxxxxxx.database.windows.net. Use this to connect to your database in SSMS.

My desktop machine has SQL Server installed. I can connect to it (using my desktop machine) using the following server name:
localhost\SQL_Express
Windows Authentication
If I want to connect to it using my Laptop, I try to do the following (ACER_ASPIRE is my computer name):
ACER_ASPIRE\SQL_Express
SQL Authentication (acerAspireUserName, acerAspirePassword)
I get an error saying the server wasn't found. How can I go about connecting to my desktop machine's SQL Server from my Laptop?
To connect to a Sql Server you need to specify two things.
1 - Server name
In this section you are suppose to provide [ServerName\InstanceName]
Server Name is the Machine Name where your sql server Instance lives. And obviously since sql server can have multiple instances on one machine you need to provide the instance name that you want to connect to.
There is an exception for Instance name if you are connecting to the Default Instance you dont need to provide full [ServerName\InstanceName] you can only use the machine name to connect to the default instance on sql server on that machine.
One thing you need to know is
localhost == . == MachineName == ServerName
These are all different ways you can tell sql server , the server name that you want to connect to.
2 - Authentication
You have two ways to authenticate yourself when connecting to sql server,
Windows Authentication.
Sql Server Authentication.
In 1st section ServerName you told sql server that which machine and what instance you want to connect to.
Now in this Authentication Section you will have to tell sql server how you will be Authenticated.
When using Windows Authentication Sql server will use your windows credentials to identify you. This has nothing to do with the Server/Machine name it is to do with the Operation system of the machine, in your case it is windows and you can use your windows credentials.
On the other hand if you use Sql Server Authentication you will have to use a Sql Server Login' andPassword`. In this case sql server will not care what operating system you have on your machine. (mostly used when you are working on operation systems other than windows like Linux, Unix, Mac). It will only take consideration the login and password you pass.
Authentication Mode
What Authentication Mode you can use? this depends on your sql server configuration when you were installing, You can set your sql server to Only Allow Windows Authentication or Mixed Mode (i.e Windows Authentication and Sql Server Authentication).
Your Case
In your Case regardless of what Authentication Mode you are using. You can use any notations in sql server SERVER Section as long as they point to your machine like
local, localhost, . , ACER_ASPIRE
But for Authentication if you are using Sql Server Authentication Make sure you are using a Valid Sql Server Login and Password.
Open the query window, and inside it execute the following:
EXEC sys.sp_configure N'remote access', N'1'
GO
RECONFIGURE WITH OVERRIDE
GO
This option is not enabled by defauld on Express edition.
By default, SQL Express doesn't support LAN Connections, only from local machine.
To use it you must configure to listen to network ports also. You can do that on the SQL Server Surface configuration tool.
I am in the process of evaluating TFS 2010. I am trying to install onto our application server which sits in a domain and runs Windows 2008 R2 Standard.
We already have a SQL Server in place on a separate Windows 2008 box that I want to use - this is in the same domain.
After installing TFS, I am using the Advanced Configuration Wizard to try and complete the setup. There are 3 bits that are reporting errors : "Database" and "Reporting".
When I enter the SQL Server details, TFS gives me this error :
TF255049: A connection cannot be made to the server that is running SQL Server. Verify that you have entered the correct name for the server, including the instance name, that the server you attempting to connect to is online, and that you have required permissions to connect... (it goes on a bit more)
The server I have installed TFS on is a web server that runs several .Net websites - all of which can connect to the SQL Server with no problem.
I have tried IP Address, machine name, instance name - all report the same error.
Has anybody been in this situation before?
EDIT : Strangely if I go to the "Reporting Server" page in the wizard and enter the SQL Server name, it connects correctly in order to get the Report Server URL and Report Manager URL. So it seems this maybe user account related?
Two things spring to mind:
You'll need to make sure the TFS service accounts have permissions on the DB server.
If Windows Firewall is on on the TFS box, switch it off for a minute or two and try again.
If that solves it, turn it back on and open the SQL ports.

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.
------------------------------ ADDITIONAL INFORMATION:

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
Database Properties File for Spring Project

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.

If you still have problems connecting to SQL Express 2008,
read this article
