I'm in the process of adding a new server as a domain controller, to supplement the existing DC and with a view to demoting and deactivating an ancient desktop PC which is pretending to be a server!
I've done the DC PROMO on the new server and all looks ok - files created in the SYSVOL folder are replicating amongst all machines.
Is this all I need to do?
On the main DC I've opened DNSMGMT and the new server is there. But there's one bit I'm not sure about.
In SERVERNAME - Forward Lookup Zones - _msdcs.DOMAINNAME - dc - _sites - Default-First-Site - _tcp
there are entries for all three servers as Service Location (SRV), but there are also Host (A) entries for the two existing servers, but not the new one.
Should I add it manually, wait for it to be added automatically or have these entries been added manually by someone in the past?
DNS isn't my strong point and I've inherited a network that really needs rebuilding from scratch but I don't have the time or staff or support. I'd love to have the time to read up on this but I'm running around the school doing several jobs at once so don't get the time to read up without being disturbed.
