Question : "Your changes could not be saved to {filename} but were saved to a temporary document named {3F8C6100}. Close the existing document, then open the temp document and save it under a new name"

We have upgraded the Virus software, and ensured that the file permissions were set correctly.  We are running Terminal server with the data on a separate file server.  Both are on the same subnet, and segment.  This is sporadic, approximately 2-3 files per week.  We have 4 Terminal Servers, all running Win2K with Citrix XP.

Jim,

Since it's only sporadic it's very hard to track it down although I suspect that the AV-software may cause it.
