I have a lot of background on this question so bear with me please. :)
I am tasked with getting our domain from 2003 to 2008 level. In order to do that I brought up a 2008 R2 server into the domain and did dcpromo to get it to "play" with the two other 2003 DCs. All is working pretty well except that I'm getting the auto-enrollment error above not because of a configuration error but because before I even came to work here the Root CA machine was taken out of service and disposed of! So the unable to contact is a true error. The machine no longer exists! I'm sure I'll have to re-setup a Root CA but wanted some guidance on the path to take on getting from where I am (broke!) to back to healthy!
thanks in advance,
Leo
