Always check the settings!

Got dragged off some very complicated and necessary development work in order to resolve a problem with a test server.

“Nothing is working”, was the cry,
“We think that either .NET doesn’t work on Windows Server 2008”
“Session management is faulty.”
“We might need to rebuild the server.”

The problem....

Well, the SQL connections used SQL username and password and the server was configured to just use NT authentication.

It’s funny how quickly people panic and look for the obscure rather than look at the more obvious causes.
