Is there possibility to that errors are up to network or up to MS SQL? What kind of information you need more? If is up MS SQL, where can be a problem?
Thank you

You could give the details like what exactly was the operation you performed to receieve this error.|||True, when and where you get this issue.
That connection error refers to the netlib protocol used to connect to SQL Server and if you are using named pipes, try changing to TCP/IP
protocol to see if that makes a difference.

Also, check to see if you have firewall enabled or any issues on network by referring to Event viewer.|||Originally posted by Satya

There is no rules when is shown on the screen. Usually comes after processing datas.

Thank you...

Connect from query analyzer and run simple query to ensure no issues on SQL part.

Try to execute similar query from QA .
