Server change causes VPN Client error

I've been doing some system changes to my RAS/VPN server to turn up IIS. Now
my RAS Clients receive the following error:

Error 778
It was not possible to verify the identity of the server


Where do I start to look to solve this issue?

Additional Note. I believe this all started when I added certificate services.
NO clients connect. Even new ones. I am not using any encryption. Just
basic RRAS services.

I had a case like this one, but can't remember the fix. Try to re-configure RRAS. If that doesn't fix the problem, re-set the router/firewall. Please post back with the result.

Already have (Several times) I've done everything short of re-installing
Windows.
I'm trying to figure out where the handshaking of names occurs in the RRAS
process. Also trying to clear out the trace logs so I can see the login
process and hopefully find a retry or something that might hint to a
direction.


All other thoughts, ideas and guesses are appreciated at this point.
