Hi,
This could happen due to many possibilities:
- Logon Credentials: Make sure that the Backup Exec service account has domain admin rights.
- Verify that there is not mismatch in the MDAC files. Please download MDAC 2.8 and reapply and verify the results.
- Run a repair database operation on the Backup Exec database. Verify the results.
If all the steps are covered and still the problem persists then run a repair installation and verify the results.
We hope this will help.
