Hello, RPC errors often belong to firewall problems, please check the port overview: http://technet.microsoft.com/en-us/library/dd772723(WS.10).aspx Additional assure to use only domain DNS servers on the machines NIC and none else.

All those things I have checked and no firewall and only domain DNS servers are used.

Now I feel a bit embarrassed, it sure helped writing the correct parameters. Thanks!
