      I have been managing a Hyper-V box for over a year, in a workgroup environment, from a Windows box. All of a sudden, I now have lost access to it.

      I receive the message: "Access denied. Unable to establish communication between HVHP01 and Laptop."

      I have verified that the HV server is added to the trusted hosts list, and I have also added my correct Windows credentials. I also checked that DCOM permissions are set correctly.

      Something caused this to stop working. Perhaps a Windows update?

      I thought I saw a step by step procedure on here once that outlined the needed steps for HV management in a workgroup environment, but I cannot find it. Anyone else ever run into this issue?

      I started having issues since upgrading to Windows 10 1709. Have you tried turning off the firewall to see if you can connect?

        That is the same version of Windows I am on as well. I disabled the firewall, but no change.

          Do you have your server listed in TrustedHosts?
          Get-Item WSMan:\localhost\Client\TrustedHosts

            Yep, it is listed in there.

              There was... Not sure where it is.

              Can you remote PowerShell to it?

                  Oh, well what more do you need? 🙂

                  Try a:
                  Get-VM | FT -AutoSize

                  ...and this will be your friend:
                  Get-Command -Noun *vm*

                      Tag this thread Windows 1709 and also update the subject line.

                      This is clearly yet another 1709 issue.

                        I also checked that DCOM permissions are set correctly.

                        Yeah, I read that 1709 completely changes the network stack. It's what supposedly causing my mis-reporting info for my AV and firewall.

                          My firewall had to be reconfigured so I can reconnect Hyper-V Manager to Hyper-V 2012 R2. I had no issue connecting to Hyper-V 2016.

                              Do you remember what settings you changed (and where) so you can connect to HyperV 2012R2 again?
