Simple check to confirm access to a Domain Controller

  • 772

I'm preparing for a battery of resilience tests on a new network (which will be hosting a mission-critical application).

As part of it, I ought to confirm the resilience of the domain controllers. We have 2 DCs in this environment, and I need to be able to confirm that when I pull the plug on one, the remaining DC takes up the slack.

What is the simplest test I can do to confirm DC2 is successfully covering for DC1?

Would something as simple as gpupdate /force suffice? Or is there a better, simple test? We've got a lot to test so the less we need to do, the better.

  1. You can run the following commands:

    Query the domain for the current Primary Domain Controller

    NETDOM QUERY /D:%USERDNSDOMAIN% PDC

    Query the domain for the current list of FSMO owners

    NETDOM QUERY /D:%USERDNSDOMAIN% FSMO

    The commands will return the active PDC and DC(s) responsible for various FSMO roles.

    I've actually found a route that seems simple enough, though I've yet to try it out.
