Hi Steve,
 
Good point, and I need to update that article to reflect the procedure. 
 
Thanks!

        Only one end should be persistent, on end should be passive
without any dial out credentials and set to never hang up.

                The only thing that comes to my mind is that they may be
set to check certificates for revocation, in which case they *might*
fail if the revocation list is not available at the Certificate
Authority.  I've not seen this or read that this happens, I'm just
guessing.

                http://www.ISAserver.org

                In the process of evaluating ISA as a firewall I noticed
that my L2TP tunnel that was working between the two test servers
suddenly stopped working, I am beginning to think that a certificate
server is required to maintain this tunnel. I did however make one
modification in RRAS, I set the connection state to persistent on both
ends. Could anyone tell me if a Cert server is absolutely necessary

                for tunnels to work when created between two or more ISA
servers.

                 

                Thank you

                  Glenn
