Anyone out there using TSM for Domino mail servers running on Windows?

We’re being told by TSM Support that we cannot use Terminal Services (Remote Desktop) to remotely access our servers to perform backups and restores. The symptom is that during the backup, it would not backup what are considered to be the normal Domino database files while a server is up and running (log.nsf, names.nsf, etc.). The log indicates the error ‘database is currently being used by someone else’.

I find this really hard to believe… Does anyone have any thoughts? Is anyone else out there using TSM on Domino mail servers and accessing their machines remotely?
