I can't replicate my AD to other server since 18/04/2009. Now, sometimes I can log into the domain, sometimes I can't. Microsoft Outlook lose connection with Microsoft Exchange but some minutes later it connect again. Some machines I can't add into the domain. When I try to add a machine into the domain, I got "The RPC server is unavailable".
I got this error after running dcdiag.
