Does anybody know of a way to disable the ability to save usernames and passwords in IE5 for a proxy server and ftp sites?

The only reason I ask is people keep adding their details to the local machine then the other users get confused because it has somebody else's name (Some people just haven't heard of a delete key)

Any help would be greatly appreciated. BTW any suggestions for NT Workstation 4.0 would be helpful too.
