Network unaccessible during NT backup

[Tom Jenkins]

Hello folks,
We've discovered something interesting (and frustrating).  We use server 
security.  When we connect to the samba box, we get a network 
unaccessible error if the NT box is in the middle of a backup.  As soon 
as the backup is finished, we can connect to the samba box.  Is there 
some setting to fix this?
TIA
