In this SF question, I asked how to determine which DC a server was talking to. We are doing some resilience testing and need to demonstrate to the client that if a DC fails, there are additional DCs available to take the strain.
nltest, I can determine which DC I'm talking to at any given time. But if we fail the current DC, how do we force the server to re-evaluate which other DCs it can talk to and then connect to one... such that 'nltest' will reflect the new DC?
Ideally I've like some sort of operation I can run within the same Windows session, but thus far we logged out and back in again. My concern with logging in/out is that cached credentials might complicate the picture.
In short, in the event of a DC failure, what is the simplest/quickest/safest way of making the server connection to a secondary DC?
