Typing path in address bar

[Kim]

My department just got XP installed today. Previously on NT, we were able to hit Ctrl G from Windows Explorer and type in the file path (network). Now with XP, because we are not Administrators, we can't type in a path. If I try to, I receive this error
"Access to the resource 'x:\folder\' has been disallowed"

This really slows down the workflow. Is there some option/permission that the Admin can set to allow us to type a path into the address bar?

If anybody has a solution, I would be most grateful!

Thanks,
Kim
