Renaming the netlogon.old with restarting netlogon service, dcdiag /fix,
netdiag /fix did not work for me.

The following are errors found on the 2 DC, SERVER1 and SERVER2, in my
domain, ACME (there is only 2 DC in the domain)

I forgot,

Symptoms: AD not replicated on DNS not working well on SERVER2
Cause by: I had to format a DC because of a hardware problem, did some
METADATA cleaning and here I am

As part of your metadata cleanup procs, did you also seize the FSMO roles to
another DC that was on the removed DC?

I'm guessing you experience those problems because you have a SINGLE LABEL
DNS NAME.
That requires additional configuration.
see:
MS-KBQ300684_Information about configuring Windows for domains with
single-label DNS names

DNS names for domain should preferrably have at least 2 levels like
domain.com or domain.local

Apparently the single label name AD DNS domain name is the issue, as Jorge
pointed out.

Honestly a fresh install is the best remedy for such a scenario. To apply
the reg change (that Jorge provided the link for) would 'force' it to work,
but it still is not a hierarchal name that DNS requires (meaning a name such
as acme.com has a hierarchy, the first level (or top level domain name) =
'com', and the second level = 'acme'. The way it is now, such as "ACME", has
no hierarchy. This causes numerous problems with AD because of DNS lookups
and registration.

Registration is affected because DNS will cause excessive traffic querying
the Root servers to find "ACME" because it thinks it's a bonifide TLD (such
as a 'com' or 'net', etc) on the internet prior to looking at it's own
database. It's default behavior of DNS to do that (Microsoft DNS or any DNS
server). That was why Microsoft disabled DNS registration with Win2000 SP4
and newer when a single label DNS domain name exists as a zone.

Also, XP just doesn't support single label domain name lookups. You would
need to apply that reg to every machine in the domain to force it, but XP
still has issues with it.

I found something interesting in KB-Q300684 about some functionality change
from windows 200 SP4. Here is why it is concerning me:

I Had 3 DNS server. One crashed: hardware failure(win 2000 SP3) . 2
remaining (win 2000 SP4 & win Server 2003 SP1).
I will try a couple of thing and will give you feed back.

Yes you are right. A single label domain name.

That is a difficult issue to overcome. Would you have the ability to
re-install a fresh domain and migrate from the old into the new?

Ace
 
Thank you M. Fekay.
You are right; it is a complicated issue. I'm planning on to reinstall my
domain right now and maybe get rid of the single label domain name.
Thanks to everyone!
