So basically we have 1 domain controller, which has the AD integrated DNS. I
set up another domain controller and replicated all the user entries and such.

Now what I want is for this new domain controller to be a backup for the
first one. And if the first DC goes offline, I have no DNS for my active
directory. So how do I set up DNS on the second DC to take over when the the
first DC hardware blows up or something?

Hello CryptiniteDemon,

For the installation of DNS set the preferred DNS to the ip from the running
DNS only, then install DNS via appwiz.cpl> windows components>networking
tools>Domain NAme system(DNS). After that give the server time for replication,
at least 15 minutes. Because you have AD integrated zones, DNS will be replicated
via AD and you just have to wait. If replication is ready, set the Preferred
DNS to itself and secondary to the other DNS server.
Also make the second server Global catalog if not done yet.

Best regards

Okay, so I did all that, and it seems to work okay except for one thing.
When I take the first DC offline, I'm able to log into any account just fine.
However, it won't let me create any accounts because it says it can't
connect to the first DC.

I made the second DC a global catalog server, so why wouldn't it be able to
make a user change?

Hello CryptiniteDemon,

Is the machine also Global catalog server?

yes.

Hello CryptiniteDemon,

Check with dcdiag, netdiag and replmon all DC's for errors and if you have
some post the complete output here.
