To Elaborate,

I created a test environment with the same versions of SQL 2000 SP4. I then did a backup of the live environment and restored it to the same-named instance on my test environment successfully. Besides the new database instance I recovered, the rest are just defaults including: Master, Model, MSDB, Northwind, Pubs & TempDB.

I then proceeded to try upgrading my test environment to SQL2005. Both systems are in the same domain and are functioning optimally. See the attached JPEG File for a screenshot of the errors I am getting. I get a .NET 2.0 error in the APP log on event viewer. nothing else partaining to SQL

That looks like a "file not found" exception with .NET 2.0.  Do you have .NET 2.0 SP1 installed?
CaxxiuxAuthor Commented:
I figured out the problem.

I had all the latest .NET version installed including v2.0 SP1. The fix was to uninstall all the .NET versions and reinstalling .NET 2.0 SP.

Case Closed.

Thanks for all your help folks.
What is .NET 2.0 SP?  The name or version is incomplete.  I need to fix this too.  Please help.
