I have uninstalled, rebooted, reinstalled, added, removed, changed, reconfigured everything imaginable related to AD: DS and it refuses to configure via dcpromo.exe.

It sits at "Examining DNS configuration" for over an hour. It adds things to the dcpromoui.log such as:

dcpromoui F04.CB4 0245 19:10:32.078 Dns_CountParentNsRecordsForDomain NS Enumeration for mysite.comon parent . failed, returned 1722

dcpromoui F04.CB4 0246 19:10:32.078 Dns_CountParentNsRecordsForDomain performing NS Enumeration for mysite.comon parent .

I'm adding the role for AD: DS with the integrated DNS; I don't have a separate DNS role.

Any suggestions other than reconfiguration by hammer would be great.

Is this the first DC you're trying to add to a new forest, or an additional DC that you're promoting? – MDMarra Jul 12 '12 at 2:18
I'm playing with AD for the first time. So I guess I'm taking my domain and adding that to a new forest. Previously I configured it as from a tutorial. I wanted to redo this as instead this time, so I could have instead of or something crazy as the default. I could also quite possibly have no clue how to set this up correctly. – Michael J.

It seems to work just fine when I do "". This is apparently the normal practice though. No clue as to why. – Michael J. Gray Jul 12 '12 at 2:43
Don't use ever a top-level domain name for your AD name unless you will never ever use that same name for an external website. – MDMarra Jul 12 '12 at 2:46

To resolve this I made AD responsible for I delegated authority for from's DNS to the DNS.

When using as the domain for AD, it simply hung indefinitely. Why? I don't really know. But I just know that any subdomain for worked fine.

If someone has a deep explanation of why this is the case, I'll mark it as the answer.

We're you literally using – MDMarra Jul 12 '12 at 11:03
I am confused. Are you asking a question or making a statement? It would be odd to ask "We are you literally using" Anyway, if you mean to ask if I'm actually using, then no. – Michael J. Gray Jul 12 '12 at 17:10
I did mean to say "were" instead of "we're". My iPad autocorrected it and I didn't catch the error. If that obvious typo confuses you, then I'd take a step back from Active Directory for a while :) – MDMarra Jul 12 '12 at 17:11
I love auto correction. But anyway, AD seems like a great thing to step away from even when understanding your typo. I'm getting pretty deep into why people get mad at it, but also why others love it. Good times. :) – Michael J. Gray Jul 14 '12 at 19:48
