As my hair grays and falls out I can't get rid of this
problem...
I am setting up a new private forest with no Internet
connection allowed.
On "ROOT1", I fill in TCP/IP settings: 1.1.1.11 /
255.255.255.0 /1.1.1.11 with Primary DNS Server 1.1.1.11.
I reboot and add the DNS Service.
I created my Forward Lookup Zones ". " (so this is the
Root Server for the private Forest) and mil and my 1.1.1.X
Reverse Lookup Zone.
Then I set "Allow Dynamic Updates to YES" on all zones.
I reboot and verify the DNS settings are good.
I DCPromo "ROOT1", creating the new forest "mil" and
rebooted.
Then I set "Active Directory-Integrated" on all zones.
Testing DNS, nslookup on mil gets no response but mil.
does?

ROOT1's name under My Computer, Properties (root1.mil)
versus in DNS (root1.mil.) are different? Note that
the "." at the end on mil is the difference on the DNS
entry.

This forest will never have Internet access and the root
hints entries are not needed. I thought you must have
the "." zone to designate this as the root server.

Eventually there will be 3 root servers in the forest so
the "DNS Island Affect" can't happen.

Please tell me what I am doing wrong!?!

Hi Adam,

What errors? You mean this message?
> The Record is different on DNS server '7.47.181.12'.
> DNS server has more than one entries for this name,
> usually this means there are multiple DCs for this domain.
> Your DC entry is one of them on DNS server '7.47.181.12',

I've seen that message often when you have mutliple DNS servers with AD
Integrated zones. So I wouldn't worry about it. The second part of the
message says it usually means there are multiple DCs for this domain and no
need to re-register, so don't worry about it.

Also, don't worry about the period. It's just the way the results are
displayed.

As for your single label DNS name, as I mentioned, can cause problems with
resolution in DNS. I would address that as soon as possible.

Hope I was able to understand your question and concerns.
