We have an intermitent problem with users saving excel97 files to our windows2003 server. Occassionally when saving, Excel looks as if it has locked up and has to be kiled off. It has in fact been creating a massive file on the server with a name composed of random letters. This file can reach 1Gb in size or higher depending on how long the user leaves it before they kill off Excel. This problem can affect win98, win2000 and winXP machines. It is only very intermitent and only affects files on network drives. If the same file is moved to a local drive and opened it saves OK. This is a workaround we have been using but we really need a proper solution to the problem.
