I have two DC. I want to replace the one that currently holds the FSMO roles so I wanted to transfer them to my other DC. However, before I did that, I tried to just change the static DNS ip on a few machines, and they were no longer able to log onto the domain, untill I changed their static Ip in DNS back to the main DC ip.
Is there something in the DNS setting I should look for on the second DC? I think I made it a secondary zone when I put DNS on there. would that make any difference?
