I am having problems using the "Backup and Restore" utility from the 
System Manager menu.  Backing up the machine which has the tape device
is no problem, but using that drive for backing up other machines on
the local net gives me an "unable to open remote tape device" error.

I have set the guest account on both machines to no password and root
group and user, but still get the same results.  This used to work
under 4.00, but doesn't under 4.01.  (we're an art school, and can't
afford an update to the current 4.05?? version until a grant comes
our way....any help would be appreciated!   Thanks!
