I've configured my Windows Server 2008 to allow the remote management (using sconfig). I am connecting (with IP addres) using Windows Server 2008 (full version, where I've configured RSAT) and Server Manager (. I am using administrator account with the password on both systems. Firewalls are off. When I try to use hyper-v role on server i got error: Cannot connect to the RPC service on computer 'xxx.xxx.xxx.xxx'. Make sure your RPC service is running. I chcecked - RPC service is working.

Does anybody know where is the problem?

  • whats the rpc error code? so can you do a "wmic /node:hyperserver-ipaddress os" from the w2k8 server thats configured for rsat? – tony roth Feb 5 '12 at 22:47

Believe it or not this is a hostname resolution issue. In a workgroup Hyper-V manager's "Connect to Server..." will NOT take a FQDN (and won't take an IP address) it must be a hostname only.

On the 2008 RSAT server in the hosts file (C:\Windows\System32\drivers\etc) add the IP and hostname of the hyper-v core server and it will work.

Microsoft really should document some of this stuff better.


check out this tool http://archive.msdn.microsoft.com/HVRemote

it helps configure authentication between the Hyper-V server and the client computer running RSAT if they are not domain-joined.


In addition to the Remote Administration rules, you need to allow access to WMI on the Hyper-V server. Like this:

netsh advfirewall firewall set rule group="windows management instrumentation (wmi)" new enable=yes
