we're having a little problem with BackupExec and don't know how to solve it. Perhaps someone could help us.

What we had:
Two NetWare 6.5 Servers with SP5 (File-/Backup-Server and BorderManager).

What we've done:
We installed a third server only for backups and moved the old be mediaserver to agent state in bestart.ncf.

We could make backup-jobs for both servers and browse through FileSystem there.
BUT: If the backup-job tries to backup selected data it says "can't connect to server" on both servers.
The BackupExec User is currently set as admin, so there are no Problemes with rights.

I can't find our problem.

Thanks for help,
