I recently added a new dc that is also the new global catalog server. I was
unable to demote the old dc using the dcpromo.
I have 2 main problems:
1. Clients are not using the new active directory server, for example i am
unable to share documents, cannot add users because I cannot find the ad when
trying to change permissions, etc.
2. Clients are also not using the new dns server (which is also the new
dc/global catalog server) to access the internet. I know this because
everytime I unplug the old dc from the network no one is able to access the
internet and they all have the new dns server added to their nic settings as
the primary dns server.
All addresses are static so there is no dhcp server. Also the dcdiag and
netdiag has a bunch of errors:
