Troubleshooting Issue with remote connectivity to Hyper-V Server 2012

Hello,

I am having trouble with remote connectivity to a Hyper-V Server 2012. Server Manager from another server on the network returns an error: DCOM was unable to communicate with the computer xxxx using any of the configured protocols.  Event ID 10028.  

If I try to connect via RDC I get the following message: Remote Desktop cannot connect to the remote computer for one of the following reasons:

1) Remote access to the server is not enabled

2) The remote computer is turned off

3) The remote computer is not available on the network

Make sure the remote computer is turned on and connected to the network, and that remote access is enabled.

---

Windows Explorer sees the server but delivers the message \\xxx is not accessible.  You might not have permission to use this network resource.  Contact the administrator of this server to find out if you have access permission. The target account name is incorrect.

I can successfully connect via RDC on a Windows 7 machine.  If I try to browse via Windows Explorer, I get the same message as above.

I can successfully ping in both directions from server to server.

Any help in troubleshooting this issue would be greatly appreciated.

This seems like a firewall issue.  Have you configured the firewall correctly?  In order for access to file shares, you need to allow access for file and printer sharing.  Just curious, what happens if you disable your Windows firewall, does everything work fine then?

OK in one place you say you cannot connect via RDC but then you also say you can via Win7, so please explain. I also assume you Hyper-V is not part of the domain but is acting only as a VM host, right? If that is the case when you are trying to RDC are you using Hyper-V-Server-Name\User-Name to connect?

The Hyper-v Server is part of the domain, but is serving only as a host.  Would it be better to not have it joined to the domain?  I cannot connect via RDC from another server that I use as a focal point for managing all servers in the domain.  What I want mostly to accomplish is to be able to connect via Server Manager on that server.

Turning the firewall off has no effect on the symptoms.

If I unjoin the server from the domain the Server Manager error (from my management server) changes to a Kerberos authentication error.

Leave it in the domain; I can't think of a good reason to remove it. Have you enabled remote management on that server (option 4 in the sconfig utility)?

Did you follow this procedure (please note that it says you CANNOT use the same user credentials for the remote server)? https://technet.microsoft.com/en-us/library/hh831453.aspx

Are you trying to connect using the server's name or IP address? If you're using the name, try the address, just to rule out a name-resolution issue.

Which of the two errors do you get when you use a different users?
