Word XP temp files do not get deleted

I am running XP and Office XP. We are in the process of migrating to Windows 2000 servers from Novell and my Personal directory has recently been moved to the Windows 2000 server. Now when I open/change/save a Word file on the server, the tempory Word file (the one that word creates while you are working on a file ~$FILE NAME) does not get deleted when I close the Word document. In some cases when I then later try to open the file, I recieve the error message that I have the document locked forediting and it will only let me open read only, create a local copy, or receive a notification when it is released.
