Redirecting local drives - dangerous??

We have two users who have to access an outside sources Win 2000/Citrix
Server, and have their local drives redirected to that session.

We have a VERY secure network, but I have NO idea how protected the outside
network is. Do we have any need to be concerned? Is there any way the
redirected local drives can cause a problem if their network is not properly
secured?

Thanks,
