I got the Hyper-V Remote Management MMC utility for Vista to make it easier to connect to my Hyper-V server and manage VMs instead of having to RDP into my server all the time. However, I'm getting the following error after it tries to connect to my Hyper-V server for a few seconds (~10s):
"RPC server unavaialble. Unable to establish communication between <SERVER> and <CLIENT>"
Both server & client are in the same domain and are connecting over the LAN on the same network (and subnet). I found this post about a possible fix, but it doesn't apply to me as the post is all about connecting over VPN/RAS... something I'm not doing.
You should confirm that your problem is the Firewall, by disabling it.
Once you have confirmed that is your issue, refer to this to find the ports that will need to be open.
I rebuilt my machine and had to go back through this. I used the info in the following blog post to open 2179 & 5900 on the client to make this work.
