SBS 2003 VPN and home access

Hi,

I was wondering if someone could walk me through the process of setting up vpn access on sbs 2003, so users can use their home computers to connect to the vpn to access their emails using outlook and the network drives. I have the vpn working on work laptops but, I think that is because their part of the domain. I have been able to get network drives but, I can’t seem to figure out how to get outlook to work over vpn from home. remote web works fine but, from time to time it goes down so vpn has been a lot more reliable.
