does someone faced error "The RPC server is unavailable" during connecting to Disk management MMC console to Hyper-V Server R2? Servers are in the same AD domain and MMC console is enabled on Hyper-V.

Thanks

You need to change the Firewall rules on both machines (NOT only the Hyper-V Server)

Run this command on both machines:

netsh advfirewall firewall set rule group="Remote Volume Management" new enable=yes

GREAT. Updating firewall on both sides was the case. Thank you –  GrZeCh Aug 29 '09 at 11:35
    
I'm still getting this. It was succesfull on my physical machine, but when I executed this command on my Virtual Client, it said: "No rules matched the given criteria". That's translated, since the machine runs Dutch language. –  KdgDev Oct 1 '10 at 10:14

For errors "RPC Server is unavailable" when trying to use Disk Management MMC or Server Manager MMC or Computer Management MMC to connect to a Windows Hyper-V (Hyper V) Core Server, please note the following: 1. Enabling "Remote Volume Management" needs to be done on both machines... the Core Hyper V Server and the client machine: On the client machine (Windows 7 and Windows 8 ... XP is no longer supported... lol ;), "netsh advfirewall firewall set rule group="Remote Volume Management" new enable=yes" will run smoothly.

On the Windows Hyper-V (hyper V) Core Server (in my case I am on Server 2012 R2), I was not eble to run the netsh command. I was able to enable "Remote Volume Management" by using the GUI tool "Corefig for Windows Server 2012 Core and Hyper-V Server 2012"... *downloadable from http://corefig.codeplex.com/releases. Version 1.1.1 was stable enough. Good luck!
