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

         Hi,

        I am having trouble getting a stable connection between 2
networks connected via RRAS. 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.
