I upgraded my SQL 2K instance with SP4 ( previously it was SP 3a) and the problem was resolved.
After few days one of over client's encountered the same problem. I ran SP4 on our client DB server too and problem got resolved.
This problem is not consistant and our other client are not facing this problem (they have SP 3a). Please help me what is the issue.
Thanks in advance

Upgrade SQL Server 2K to SP4

Did you ever get these problems resolved
I am also getting both errors 17066, and 18052.
As for the L:\ Drive problem, that is not referring to anything from your machines, that is where the source was located when it was compiled by Microsoft.

One of our customers has also had this problem after an upgrade to SP4 from SP3a.
