We have Win 2K8 AD/DNS/DCHP (SRV1) server and one Win 2K3 AD/DNS. None of these are R2
We are trying to get decommission the 2003 server.
I've created another 2008 (non R2) SRV2. It had been running as an AD server, but in a instances when SRV1 turned off no-one could log on to their computer. I just made SRV2 a DNS server. From what i can tell it is replicating ok. I just followed the standard prompts when adding a DNS role.
SRV1 is virtual server while SRV2 is physical. We practiced a test power down with our UPS, but when SRV1 shutdown again users couldn't log on to workstations, and workstations couldn't go out the internet. Also our client PC's only show SRV1 as their primary DNS server. I don't think DCHP is sending out the IP address of SRV2.
I've checked SRV2's IP address is in the Name Servers for our Zone and it is.
