Our secondary DC crashed, and i had to create a new secondary dc as many users have it configured as their preferred DNS server.
The promotion of the new secondary keeps failing whenever I use the same IP as the dead DC.
PS: I have removed all references to the old dc on the domain before recreation.
I tried changing the IP after using a new IP to create, but it stops replicating to the PDC once that's done.
What do I do? manually changing the DNS for all users will be very tasking.
