I often work in two offices, and use my laptop in both. My laptop is configured as a member of a domain at head office, which has a full blown Win2000 setup and a hardware firewall. The other office uses SBS2000 and is protected with ISA server. I want to be able to access resources at head office when I'm in the other office. My laptop is a member of a domain called PIWI-1 at head office, the SBS domain is called Wildair. How to I set up the ISA server to allow VPN traffic from my laptop when I log-on to my laptop with my PIWI-1 userid? I have VPN working when ISA is diabled, so I guess it's a matter of authentication and authorisation. I'm very new to ISA so details would be appreciated. Thanks in advance Dave Arkley
