I’ve recently moved from [Windows 2003-32 bit, IIS 6 .NET 2.0] to [Windows 2008-64 bit, IIS 7 .NET 2.0].
Everything seems to be working fine except from the HTTP 500 error I am getting periodically and I also get timeouts in my database MSSQL 2005-randomly and on any on random stored procedures (DB is optimized and working fine-all stored procedures are working ‘0s’ on the sql).
Any ideas how to resolve this error HTTP 500 error?
First of all get error info. Error 500 is a common error for any unhandled error.
There are some common causes and concerning migration I’d try switching application pool to classical mode. If this helps, you need to migrate your web.config to support IIS7 pipeline (some info here).
