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

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.

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

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
