I'm testing a Exchange 2012 VM recovery in a Hyper-V test server. I have this VM, 2 DC and a Exchange server:

  • SRVDC1 (pdc, nm, rid)
  • SRVDC2
  • SRVEX2

As far as I know I need to recover also a Domain Controller to let exchange run, then I choose to recover only SRVDC2 (non-pdc) to simulate a pdc failure. This DC cannot start the AD services, DNS and so on... maybe because it is not syncronized with its pdc. Is there some way to run the non-pdc domain controller alone?

EDIT: I also tried to seize roles from dead DC1 to DC2, but AD services and DNS doesn't start.

If they are both Global Catalog servers (and the respective AD DC Roles), both have DNS and Exchange is configured to point to both DNS servers, I can't see there being an issue.

  • I don't know why, however the DC2 after a reboot without its PDC doesn't start AD services and DNS. I also tried to seize all roles to DC2 (so now it is the PDC) but it fails again to start services.... for example if I run netdom query fmso I get "specified domain either does not exists or could not be contacted" – Tobia Jul 02 '14 at 10:57
  • Sounds like a DNS issue make sure your NIC DNS are set to itself and the other domain controller. Also have a look in the event logs for AD DC errors. – Rhys Evans Jul 02 '14 at 12:28
