Hi Steve

       according to u I placed 2 computers in one OU and
assigned group policy for that OU. Assigned IPsec polocy
as Secure server for that OU

     After some time both machines are unable to
communicate with each together as well as domain
controllers. Domain controllers are able to talk each
