I am trying to create a Site-to-Site VPN from an Enterprise installation to a Standard installation. Now, during initial config of the servers it all worked hunky dorey, but since changing the Enterprise side to a 3-leg Perimeter, I am getting the following message at the Enterprise side (the Standard side has not been changed so the orignal policies still exist).
"One or more computers in this array cannot be added to the list of valid remote access servers in the Active Directory. Before a computer can be used as a remote access server, the domain Administrator must complete this task."
Except that the 2 array servers are in the RAS AD security group. I have quadruple checked local accounts and passwords.
The Enterprise array members have 4 NIC's - External, Internal, Perimeter, Intra-Array. One thing to note is post-installation of ISA, I renamed and configured all the NIC's as per Jason's blog entry. Does this cause problems if done post-install?
