I have approx 15-20 users IE5.0 or IE5.5 where they continously lose thier proxy server settings. Either they go away all together or the settings remain and the check mark gets undone. No one has dial up access to the internet I have tried editing the registry to lock the address but then the check mark goes away. I have tried setting the proxy server in Safe Mode with no luck. Does any one no of a solution. This is happening on all windows machines Win 95/98/NT/2000 Pro. FYI we have Lotus Notes and Novell Client on all machines.
