I lost in SQL Server 2000 with SP3a on W2K Server Ole DB Provider.
When I trying make new linked server I cannot select Provider name,
because menu is empty. Existing link between SQL servers returning error message Error 7302: Could not create an instance of OLE DB provider 'SQLOLEDB'. OLE DB error trace [Non/interface error: CoCreate of DSO for SQLOLEDB returned 0x80004002]. I tried completly uninstall SQL from server and I installed server again without success.
