Scenario: Windows Server 2012 with the Remote Access role installed. IP set to static, registered DNS. 3 domain controllers, all running Server 2003 (I suspect this may be the issue)

Done so far: DNS registered, firewall turned off after IPsec was applied. Able to ping all 3 DC's with no issues

Problem: Going through the DA wizard generates this error. I am logged in as a domain admin, verified that I can ping the DC, verified IPsec allows me to contact it. Since this version hasnt been readily deployed yet, there isnt much help available online from what I can find.

Any assistance ayone could provide would be greatly appreciated. I am still new to the server world as far as things are considered. I would fit, user wise, between Superuser.com and serverfault.com (junior admin)

Thanks to anyone who may be able to assist!
