      I have several VM's that are not syncing with domain time correctly. They keep jumping forward about 6 minutes, and then jumping back. This is happening repeatedly. Is there a way to force these domain members to stay on domain time? The DC is not doing this and is set to get it's time from pool.ntp.org

        Is your hypervisor time off?

          Are they being set to sync with the VM tools for their host platform? Then being set back by Windows as part of being in AD?

            Exactly - if the VM's are pulling time via the hypervisor tools - then checking against AD, they will continue to bounce.

            you should disable syncing with the host hypervisor.

              If your DC is reaching out to pool.ntp.org, I would set your hypervisor to hit the same time server.

                  Those are generally the same thing.

                    The hypervisor is a type 1, yes? Hyper-V, ESXi, XenServer or XCP-NG or KVM? (the hypervisor and host should be one in the same)

                        ok, host time was wrong, but it was way wrong, more than the 6 minutes. How do I tell ESXi not to sync with host?

                          That's the wrong thing to look at. You want your VM's to not sync with ESXi. And maybe you don't want ESXi to sync with the hardwarde (because you can sync to the internet).

                          In the settings for VMWare tools in the VMs there should be setting - sync with ESXi or something... disable that.

                            You can set your guests time server to be something other than the host.

                              ok, that setting was already disabled in the VMWare tools options, so that's not the problem.

                                Fix it anyway. The host time needs to be right.

                                Also, your VM sets time on boot to that even if that option is not checked. Until the VM network comes online and sets itself to whatever source it has.

                                  The host time has been set correctly, but I don't think that was the source of the problem. Time Sync.PNG

                                    But this VM has not been rebooting, it just keeps changing while running.

                                      Didn't say it was. Just saying fix this problem also.

                                        oh ok, I understand.

                                        I feel like maybe there is some sort of group policy that should be set to make this sync work correctly, and that somehow mine is not set. Although, this problem is only recent.

                                          I just realized it must be related to this host. I recently moved the main VM that I am having a problem with to this host.

                                            Windows could be checking hte hardware clock. This has nothing to do with VM tools settings.

                                            And your host (the hardware) was off.

                                            But Windows was not moving it too far..

                                            Answer: Windows sucks.
