Anyone know anything about Virtual Private Networks? We've recently had one set up for remote access to the office, but whenever we use it we find we can't map to any network drives. We don't have this problem using direct dial-ups, and as far as we can tell, all the obvious stuff is configured correctly (DNSs and all that).

Now, I'm not going to go into huge details about this because I don't really know them. All I want to know is: has anyone had this problem before, and if so, how did you solve it?

Thanks.
