Remote Access Routing Questions

Hi,
I am trying to understand the VPN routing and how it is different between a
"Connect to SBS" connection, made from a remote connection disk, and a VPN
connection set up manually.

First, these act differently. For example the "SBS" connection can access
\\companyweb but the VPN can't, but both can access <servername>.local or
even companyweb.<servername>.local. Why can't the VPN access \\conpanyweb?
How are these not the same thing?

The SBS connection can't access an external web site. What makes the server
perform the routing?

I have configured the VPN connection to allow direct local access by
unchecking "Use default gateway on remote network". I don't know how to do
the same with the "remote connection disk"? How do I set the parameters of
the remote connection disk?

On a somewhat related note - how would I create a VPN user that is not an
SBS user (For access to a secure web site, CVS server, etc).

Thanks!
