cannot delete file: access is denied

Ocassionaly, when I try to delete a file from our Netware 5.x file
server, I get the message "Cannot delete <filename>: access is denied"
"Make sure the disk is not write protect or full". This disk is
neither. This happens ocassionaly. Perhaps 10% of the time. Sometimes
if I try to delete the file again 2 or 3 times, I finally can.
Otherwise, if I wait for a few hours I can delete the file. Nobody
else has the files open.

Environment:
Acer TravelMate C100 Tablet PC
- have latest WinXP service packs
- have latest BIOS
Novell Netware 5.x server
Novell Client 4.83 SP1.

Other info:
- can be any file in any folder.
- happends on all 3 Netware file servers
- error happens if attempt to delete file from Windows Explorer or via
"My Computer" icon.
- error happens whether drive is mapped or go directly via the network
browser
-

 

You'd probably be best off finding a novell network group to post in.
Might be a couple suggestions here, but your issue isn't
tablet-oriented, and you may not get any good suggestions in here.
