Hi Christer,
The error may occur if the VERITAS Backup Exec (tm) service account has not been granted the correct privileges (including privileges for group policies).
The account should have administrator rights on the server being backed up.
Also, the following rights may be assigned to the account through the group policy:
1. Act as Part of the Operating System
2. Backup Files and Directories
3. Create a Token Object
4. Logon as a service
5. Manage Auditing and Security Log
6. Restore Files and Directories
7. Take ownership of files and other objects
* also try enabling the restrict anonymous keys on the remote server as well as the media server with the help of the following document:

Restart the backup exec services after enabling the key.
Hope it helps!
