ie5 authentication issues

Hi
We are having a problem with authentication on our reporting server. If the
user connecting is using IE version 5.0 they get a not authorised to view
page error (see below). It works fine for this same user if they use a
machine with ie 5.5 or greater. Other users also have the same problem but
always only if they are using ie5.0. Does anyone no what is causing this? Teh
users connect to the server using the standard
http:<reportservername>/Reports interface. Thanks
