RPC Server unavailable

RPC Server unavailable

Hi!
 
On most of our virtualized (VMWare) Win2008 servers we get the "RPC server unavailable" when trying to set up WMI based monitoring.
 
RPC server is up and running, so is WMI and DCOM on all the servers.... Firewall is disabled on all machines, and the servers are on the same subnet as the OPManager server.
 
I have searched through the KB articles and the forums, but so far no luck in finding anything that might resolve the problem.
