Run this via Query Analyzer:

SELECT ServerProperty('ProductVersion'),

           ServerProperty('ProductLevel')

I'll bet it will return 8.00.311 and SP1.

I suggest you download and install SP3a for SQL Server. That might help solve your problem. (SQL Server is now up to SP4, but I would only apply SP3a at this time).  Once you get everything working, then look into applying SP4.
