Running windows 2003 SP1 with SQL Server 2000 SP4. Upgraded Crystal Reports 11 to both servers, once completed, started to get OLE DB SQL SERVER errors on 1 of the Nodes. I have checked registry settings for permissions which may have been changed during CR upgrade. Re-install SP4 for SQL Server 2000. Still have the same problem....Possible next step is the re-install of SQL Server 2000 Any thoughts ??????
