I'm trying to connect to my local machine name as "Server Name", and giving windows authentication, but its throwing some error:-
"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: Named
Pipes Provider, error: 40 - Could not open a connection to SQL Server)
(.Net SqlClient Data Provider)"
Please note previously it was connecting all well some few months back, but now it throws error. I tried lot of alternatives provided around the web, but nothing worked.
Did I miss something ?
If the service is running on your local machine, try connecting with "LocalHost" as the server name.
Also, did you check that the service is running?
There are several reasons for this to happen:
Check if your SQL is up and running
Check there is no firewall messing around
Check on the configuration manager if sql services is up
Check if TCP/IP is active on the configuration manager
Sometimes, I know is weird, but his error shows up if you haven't configured your server for mixed security (both windows and SQL Server). Try connecting with a windows user with SA permissions and activate SQL authentication as well.
To do this, open SQL Server manager and connect with the SA user, right click on the server properties, check the "Security" tab for "SQL Sever and windows authentication mode"
Check this blog post that will lead you from some of the points I told you.

As the error states "network-related or instance-specific error" its related not being able to find the instance.
This maybe due wrong instance name, Check the spellings of the server that you are connecting to.
You may have installed a named instance like sqlexpress in that case the server name should be {YourServer}\Sqlexpress.
You can get your instance name by going to services, if its MSSQLSERVER you can connect with the machine name else you should provide the correct instance name.
Please refer the screenshot below.
If you are connecting to another machine check the network configuration of the instance by going to sql server configuration manager. If the status is disabled you can connect from outside.
If that also fails better check the firewall settings
I've installed tigertoolbox from Microsoft and I'm using SQL Server Performance Dashboard Report daily.
It's very useful and I suggest you to install it if you are not using it yet.
BTW, when I connect to localhost everything works smoothly but when I'm trying to connect to another SQL Server instance on the network I receive the error
An error has occurred during report processing. (rsProcessingAborted)
Cannot create a connection to data source 'DataSource1'. (rsErrorOpeningConnection)

(provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Access is denied
The answer is very easy: I can easily connect to localhost thanks to my credentials but I need to enter user/password for a remote SQL Server instance.
How can I ask to SSRS to prompt user and password for remote SQL Server instance?
The problem Cannot create a connection to data source ‘DataSource1’. (rsErrorOpeningConnection) is even mentioned in the comments on the official Microsoft page but it's not mentioned how to fix this issue.
Check if you are running the SSRS on the default port of Server. If not, inform the port in the connection.

Server instance
That is NOT the answer.
The error tells you that your server was not found, so it cannot be authentication error, the server is not reached so it just cannot authenticate you.
You should check your connection string if it's right. if it's correct, it can be firewall or your server is not configured to accept remote connections.
So for whe first thing post here your connection string, it looks like this:

Hello I'm trying to connect to SQL server with Microsoft SQL server management studio. However when I try to connect I get the following error:
Cannot connect to DESKTOP-QELGJNT.

Usually you have to set up a server first before you can connect. How can I do this with SQL server management studio, if this is the reason I get this error.
I also checked under services but I couldn't click start on SQL server vss writer. That is the only sql file running I found.
I checked on YouTube and stackoverflow on a similar subject, however it didn't provide the solution for me. Could anyone help me?
This question can be helpful to others as well who have similar problems with SQL server management studio.
Is your SQL Server installed on your local computer? If yes.
Check your SQL Server Configuration Manager. If SQL Server service is in Running state.
It may possible your SQL Server service for that instance is stopped. There can be may reason one is due to service conflict with other. What you can do is
go to SQL Server Configuration Manager (type on start menu it will appear)
On left pan go to SQL Server Services
SQL Server() is running if not right click and start
If this will not resolve the issue then do check TCP/IP is enabled or not?
To enabled that
Open SQL Server Configuration Manager.
In the left pane, expand SQL Server Network Configuration, and then
click Protocols for MSSQLSERVER.
In the right pane, right-click TCP/IP, and then select Enable.
Double-click TCP/IP. The TCP/IP Properties dialog box is displayed.
On the IP Addresses tab, identify the block corresponding to the IP
address that you want to enable.
In the Enabled field, select Yes.
In the TCP Port field, enter 1433.
Click OK.
I configured the SQLAzure database. I configured the firewall for my IP and when am trying to connect to that database from my local using SQL Server Management studio, getting below error
TITLE: Connect to Server Cannot connect to XXXXX.database.windows.net.

How to resolve this issue?
Please also check network protocol when you connect to Azure database via SSMS. It seems you are using named pipes and TCP/IP is excepted.
Hi Bravo are you able to browse the instance via Visual Studio if you have it installed?
Can you also confirm that you are not behind a corp firewall that blocks 1433 outbound?
Really minor thing but the title of the error has a trailing "." which if that is the machine name you are trying to connect to won't work - it may just be appended by the error message.
You can try a few things:
Ensure SQLAzure database name is correct (the error that you posted translates to name doesn't even exist)
Try adding port number at end of the connection
XXXXX.database.windows.net,1433
If the issue still persists, try pinging the SQLAzure from your local machine.
I installed SQLManagementStudio_x64_ENU from Microsoft site on my Windows 7 Home Premium.
It gave me compatibility warnings but I still installed because Microsoft site specified that I would receive warnings but suggested to click on Run Program, which I did.
It was successfully installed. I checked Services.msc, and I can see two SQL Server services are running. I checked SQL Server Configuration, and I can see services running under automatic mode, and the agent is off.
When I open my management studio and try to connect using "Server name" option, I can't see any server instance in browse option. There are no servers to connect. I am not able to connect to the database engine. I have tried at least 10 times, but still, it's not allowing me to connect.
I get the following error:
A network-related or instance-specific error occurred while establishing a

Can someone help me with this problem?
In the Connect to server dialog of the SQL Server Management Studio (SSMS), type <your machine name>\SQLServer2008 to connect to SQLServer2008 instance. Otherwise, type <your machine name> alone in the server name text box to connect to the default instance SQLExpress.
