Question : Error: (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe

My development machine (Windows 7, IIS, SQL Server Express 2008) has been 100% fine for 5 months - but today it started throwing the following error Intermittently. It does it from 2 separate websites (both working fine on production server & before on dev machine) - and sometimes in SQL Server Enterprise Manager.

A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)

I have googled it but can't find any solutions that work - any ideas most appreciated - Im going crazy here.

Thanks.

Answer : Error: (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe

OK Solved it (with help from Microsoft)

Somehow max connections had got set to 3. Run this script to get the value & fix it
