Re: [Exchange] Exchange keeps looking at a old DC
Sounds like the three "old" DCs weren't properly demoted from the domain and they still have services entries in DNS.
I would make sure the two current DCs hold all 5 FSMO roles then I'd clean up DNS of any entry referring to the "old" DCs.
That should get you started on the way to recovery.
