In the midst of trying to utilize processor power, I created a fault tolerant DNS server a while ago. Since then, I've been trying to add another controller for exchange. So I thought I would revert back to a single primary DNS for the meantime, and now I'm balancing on a thread.
The server I thought I uninstalled DNS, is still acting as DNS. And now the PDC does not resolve.
Can anybody walk me through, I'm overwhelmed and can't think straight. I'm afraid if anyone restarts their machine they won't have internet.
Okay, so from the beginning: I was configuring Exchange on a new server 2008. How it happened I don't know, but it started to not resolve DNS. (exclamation mark on NIC) even though everything was static. So ultimately I decided to remove the server from the problem, because I noticed DNS was in disarray if I used the DNS IP of the first server. This is when I tested with
nslookup on each DNS server. I had uninstalled DNS from the second server, but
nslookup was still resolving with that IP address, which has me all wound up because I don't understand. So, since the first DNS server isn't resolving, I'm assuming if the second one isn't configured right I'll loose internet. I'm just confused and don't know where to start troubleshooting.
I guess my ultimate question is how can I return and verify my original AD DC to it's DNS function?
