Inner exception: SQL Server does not exist or access denied.

After installing AyaNova on a server with SQLExpress I installed on a client computer and got the following error when I tried to start AyaNova:

[b]AyaNova was unable to start

Depending on how early in startup the problem occurred,
a detailed log of the problem with suggestions may have
been saved to the file AyaLog.txt
located at: file:\C:\Program Files\Ground Zero Tech-Works Inc\AyaNova 3

Error details:
Unhandled Exception:
Exception has been thrown by the target of an invocation.
System.Reflection.TargetInvocationException
Inner exception: SQL Server does not exist or access denied.

After working with Joyce, it turned out the problem was my Windows XP Firewall and my Norton Antivirus 2006 Worm Protection on the Server. As suggested in this article:

I created an exception for the sqlsrvr.exe and it finally worked.

Thanks for all your help Joyce!
