Windows 10 Hyper-V can't connect to Windows Server 2012 R2 Hyper-V RRS feed

  • Question

  • I have 2 physical servers running Windows Server 2012 R2 with several Hyper-V VMs on each server.  All devices in our organization run Symantec cloud based Endpoint Protection.  When I am logged into either of the 2 servers, I have no trouble connecting to a VM on the other server.  But when I attempt to connect to either of the 2 servers VMs from Windows 10 Hyper-V, I receive an error message that the "RPC service is unavailable" on the remote computer after it fails to connect to the remote virtual management service.   I checked my group policies and there no issues that I can find.  Am I missing some ports I should open on Symantec Cloud Endpoint Protection?  Any ideas?  Thanks.

  • Hi Emr88,

    >>All devices in our organization run Symantec cloud based Endpoint Protection.

    If possible, uninstall or disable the antivirus application and try again. I have seen lots of issues caused by the application.

    >>When I am logged into either of the 2 servers, I have no trouble connecting to a VM on the other server.

    Do you mean connecting through Hyper-V manager?

    Diable the firewalls on Windows 10 and Hyper-V temporarily.

    If you have clients running Windows 8.1, disable AV application and try to connect.

    Best Regards,

    Leo

  • What version of Windows 10?  Earlier releases had a known problem with remote management of Hyper-V 2012 R2 systems.  Issue the Winver command on your Windows 10 system.  If it is not showing 1511, you need to upgrade to fix the remote management issues.

  • Yes, I mean connecting through the Hyper-V Manager.  Oddly enough I can connect via RDP.  Since all computers are running Symantec, I don't understand why the servers have no connectivity issue but the Windows 10 workstation is unable to connect.

  • Thanks, Windows 10 is 1511.

  • Thanks everyone for their help.  This problem has been solved.  I loaded Hyper-V Manager on 3 other Windows 10 machines that had no issues connecting to the servers.  Based on Leo's response, I returned to my original machine and removed Symantec Endpoint Protection.  After the workstation restarted, it connected without issues.  I re-installed Symantec Endpoint Protection, restarted and it still connected via Hyper-V Manager.  It would appear the issue was a corrupt Symantec Endpoint Protection endpoint.
