    Good luck fella!

    What doesn't kill us makes us stronger, good learning experience too.

    You'll get through this and be stronger for it.

    Morning All,

    I have created DC3 this morning on the working host and have replicated data across from the existing DC. AD and DNS are now fully populated.

    Just applying updates to server now and will reboot host later in the week or at weekend.

    Im guessing i don't need to do anything else? Aslong as DC3 is up when the second host is rebooted we should be good to go?

    From a cluster starting view, you should be okay, you may want to consider the plan of action if the host doesn't reboot properly and the hosted VMs fail to failover but that is unlikely.

    Make sure your online DC is pointed to by your servers for DNS. Otherwise they won't work on the reboot as they won't see the domain even though it is there.

    You really shouldn't have DC's virtualized.

    I keep both of mine on physical boxes.

    EDIT: sorry didnt realize you were already building another DC

    I have 3 DC's two virtual on two different hosts and 1 physical.

    Out of interest, why didnt you just RDP into one, shut it down then add the VHD on a different host and start it back up?
    Also, could you manage the VM's from the hyper-v console on the other host or does the dead service stop management full stop?

    I am certainly going to add a physical DC to the infrastructure, just haven't had chance yet as only been here a month.

    If i shut down the DC in question to do that, i can't start it back up due to the error so if it didnt work, id have no DC.

    The dead services stop the management full stop, heres what i get:

    Your only shutting down 1 DC, the second is still running right?

    If the move fails you still have a DC working while you create a physical DC. Its a 10 minute job, rdp > shutdown > connect VHD to another VM on the working host > start VM

    The second one is on that host too Chris. Bit of a nightmare!

    However, i just spoke to the company that put the hosts in and they have said there IS another DC installed on the DPM box as a VM (physical hardware off the cluster) which is already the primary DNS server so we should be fine to shutdown machines, reboot the host and bring everything back up!

    Sorry i didn't know this being new to this network, maybe problem solved!

    But you would only be shutting one down, the other would stay up for the time being.

    Both DC's are on the host which needs restarting though so no DC would exist when host is restarted! There is however now a third DC i didnt know about so yes, now the situation is we should still have a DC available when restarting the host.

    Thats why you were shutting ONE DC down, leaving one up, moving it to another host, starting it, then worrying about starting the physical host after.

    In our cluster, the dcs are the hosts, I was advised not to virtualise the dc's guess this is why. I shit myself whenever I have to restart even one of the failover cluster hosts. They have a secret way they like to be restarted, and I never get it right... Plus I transfer the vm's to one host, and have a couple of times, restarted that host instead of the empty one. Now I check it several times!!

    Hi

    Just to let you all know we managed to get everything working without having to reboot the host! I killed the associated svhost service which unstuck the windows management intrusion service and allowed me to restart all the services successfully.

    I can now manage machines again and the failover cluster is active

    Regards
