Update

After working with this problem the Error message popup that comes up is
"Document not Saved". Also Excel will write the file name to the server but
the file is empty.

After the April Office 2007 updates, Excel 2007 is unable to save a
spreadsheet to a Windows NT 4.0 Server's shared folder. Has anyone else come
across this issue and if so come up with a fix? Currently having to save the
file to the desktop then copy to the shared folder. This issue is showing up
on multiple machines.
