Have a Win2003 Server as a file server and multiple people connect to a mapped drive and save documents, mostly MS office (2007, 2003). All of a sudden, many people are complaining that thier files are gone. I notice that there are tons of XXXXXXXX.tmp files in all folders and the missing files are actually these files... if I rename one to XXXXXXX.xls, it's the missing file. This server is 5 years old and never had any trouble. There is nothing in the app or system logs... Any ideas?
