IE6 on Win2K Won't Access SSL Pages

[Pat]

Suddenly, Internet Explorer 6 on Win2K Pro won't browse to any SSL webpage.
Administrator accounts can access SSL pages, but non-administrator accounts get the IE
"page not found" error.

I've recently had to fix corrupt user accounts, and these accounts are the ones that
can't access SSL pages.

Firefox can access SSL pages fine.

Any help would be appreciated!

Thanks,

Pat
