Can't remote to servers, but can console in VMWare, Active Directory problem?

I am having a variety of problems.  For some reason, my dhcp server deauthorized.  I tried to reauthorize it, and even tried to bring up another dhcp server, but they couldn't authorize with Active Directory.  As a work around, we put dchp on our switch.  

However, since the problem, when I try to remote to any of my 2003 or 2008 servers using RDP I get an error that says access is denied, contact my administrator.  However, I can go in Vsphere and console in using the same network credentials with no problems.  Has anyone ever run into this?

I would check services. Sounds like rpc service is not running.

RPC is running.

RDP issue: check user rights assignments on server for what groups are allowed to logon through terminal services.
DHCP authorize issue: probably logged on as user without permission to write in AD container under NetServices storing objects for which servers are authorized. Logged on as DomainAdmin?

Thanks for the suggestions.  We figured it out.  We had restored our domain controller from a snapshot in VMWare.  2003 does not recognize this as an acceptable backup, and started failing.  Somehow during the meltdown, the system password used between dns and AD was changed, and all services started shutting down.  Had to get a Microsoft expert to repair it for us.
