I'm having a few problems with files being locked on the server which is
preventing them from being backed up.

I have an application that has a series of access databases that are kept
open all the time but are in use infrequently.

All of the databases are shown as in use by the same:
connection number
lock status is not locked
log status is not logged
open for read =1
open for write=1
there are no deny read or writes

I can copy some of these down to a workstation but not others.

The backup also had the same problem with an open Excel file last night
(backup is done by Backup Exec 9.1 with an open file agent and there are
no other skipped files)

Any ideas?
