NW65SP7, WinXPSP2, Client 491SP4

This started happening a while ago, and I'm not sure what caused it, but
when I attempt to rename an executable file on a network drive, I get a
"Novell Message Popup" message that says:

Message from server MYSERVER:
Received Wednesday, February 27, 2008 10:11:51 PM:


I turned off AV on the server and rebooted, still get the message ... I
have eTrust AV on the WS, but I have that on all WSes with the same
setting and it doesn't happen elsewhere, so I'm thinking it is something
to do with the client?

Any ideas?
