The request failed or the service did not respond in a timely fashion?

I have the following error while I connect to SQL Server 2008 Management Studio with Windows authentication.

"The request failed or the service did not respond in a timely fashion.
Consult the event log or other applicable error logs for details."

Is anybody tell me why i am getting this error, whereas my SQL Server is running under network service built in a/c????

I googled it but not getting solution..

Thanks

Had the same problem, I fixed it.

1. Open SQL Server Configuration manager
2. Click on the SQL Server Services (on the left)
3. Double-click on the SQL Server Instance that I wanted to start
4. Select the Built-in account radio button in the Log On tab and choose Local system from the dropdown menu
5. Click apply at the bottom, then right click the instance and select Start

Above mentioned issue happened in my local system. Check in sql server configuration manager.
Step 1:
SQL server Network configuration
step 2:

• Protocols for local server name
• Protocol name VIA Disabled or not..
• if not disabled , disable and check

.. after I made changes the sql server browser started working

This really works - i had verified lot of sites and finally got the answer.

This may occurs when the master.mdf or the mastlog.ldf gets corrupt . In order to solve the issue goto the following path.

C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL , there you will find a folder ” Template Data ” , copy the master.mdf and mastlog.ldf and replace it in

C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA folder .

That's it. Now start the MS SQL service and you are done.

If you are running SQL Server in a local environment and not over a TCP/IP connection. Go to Protocols under SQL Server Configuration Manager, Properties, and disable TCP/IP. Once this is done then the error message will go away when restarting the service.

If you recently changed the password associated with the service account:

1. Start SQL Server Configuration Manager.
2. Select SQL Server Services in the left pane.
3. Right click the service you are trying to start in the right pane and click Properties.
4. Enter the new Password and Confirm password.
