A couple of days ago Ive joined new server(Windows 2008 R2) to the domain as DC and started receiving following error. I captured screen of Vegemite-CA and I was wondering if that selection is the solution and if I install that will it effect my Exchnage 2010 certification insfructure?

Hello, have a look into, just to compare ignore the OS version, basically they share more or less the same source code: http://support.microsoft.com/kb/947237 Also make sure that no firewall is blocking access. Often PRC errors belong to communication problems.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
