Hi Sonny, Is this a gateway to gateway VPN? Did you use the Local and Remote VPN Wizards? Thanks!

Network A has RRAS configured on a Machine with ISA installed on it. Network B also has RRAS configured on a machine with ISA installed on it as well. Network B is a Subnet in the same domain as Network A. In network B, Laptops connect to resources in Network A via A VPN through the internet between RRAS Server in Network A and RRAS server in Network B. However, one of the Laptop has XP Home Edition installed on it so therefore cannot login to a Domain. To get around this limitation, a VPN client is created on the Laptop with XP Home Edition terminating at the RRAS in Network B so that it can be authenticated on the Domain and access all resources available. This will work fine so long as ISA server firewall service is disabled. On the other hand if the ISA firewall service is enabled and running, this will still work but very unstable. The following error message is reported together with microsofts proposed solution while the VPN connection is up while the ISA firewall service is running. This error only occurs on the RRAS server in Network B.
