You can, he can't.
Are you sure he can if you make him administrator? Tried it? Or could there be some other cause?
Other question, same intention: does this happen with all non-admin users throughout the network? Or with all non-admin users (make a new one to test!) on this particular PC?
Tried repair IE from Config Panel? From this user, I should say (after making him administrator temporarily).
Just some suggestions. If things aren't clear, you have to experiment to find something.

A user can not print web pages from IE6. If I sign on as administrator the pages print normally. These workstations are restricted. Users do not have full access to everything. Where is IE trying to write a temp file that the user does not have access to?
