Thank you for posting this, you have at least a single-label domain name
(provided the primary DNS suffix matches the Domain name in ADUC) this is a
known issue for single-label domain names and will require registry entries
not only on the DCs, but also on every client with Win2kSP4 and later, WinXP
and Win2k3.
826743 - Clients cannot dynamically register DNS records in a single-label
forward lookup zone:
http://support.microsoft.com/?id=826743

If the primary DNS suffix does not match the AD domain name and the AD
domain name is the required multi-label format i.e. 'domain.com', then you
have a disjointed namespace, which also causes this behavior and there is a
script that fixes this.

Name

hi kevin
i don,t think i have a disjointed name space.
My dc name is matching my domain name.Users can access the
domain.i can send and recieve emails on my exchange 2000
server,but i cannot create new mailboxes,it is giving
error that exchange 2000 cannot find global catalog since
the srv records are missing from dns zone.i deleted the
dns forward lookup zone on both my PDC and BDC and again
recreated it as active directory integrated.stopped and
restarted netlogon.i had also my reverse lookup zones
configured on both servers,i didn,t delete them.still i
can,t get the srv records back.
when i run dcdiag/test:dns on my PDC,It si showing error
:\Documents and Settings\fasahat>dcdiag/test:dns

Re-read my post, it was an either/or post, make the registry enties for the
Single-label name.

hi kevin
i don,t have service pack4 installed on my domain
controllers,they are running service pack 3.I think this
article is related to computers that have sp4 installed.
Kevin when i try to force replication thgouh Active
Directory Sites &Services, it is giving me DNS LOOKUP

I can see these resource records in c:\WINNT\SYSTEM32
\CONFIG\NETLOGONDNS.
why can,t i see them in my forward lookup zone.
i don,t want to rebuild my domain.
save me guys.

Unfortunately, that would be the best way to resolve this,

If it were me, I'd build a new domain on a different DC with a valid DNS
name, set up trust between it and the old single-label domain, then use ADMT
to migrate all the user and computer accounts to the new domain with the
valid DNS name.

kevin,
how do i point my exchange 2000 from my existing domain to
the new domain which i will build and transfer data through
ADMT.
CAN YOU GIVE ME THE LINK HOW TO TRANSFER USER ACCOUNTS and
the rest of data using ADMT.
I will really appericate it.

I can't give you the exact process, I know you'll have to run /adprep and
/domainprep on the new DC, just like you did when you originally installed
Exchange. It may just be a matter of add the new DC to the Directory Access
tab in System Manager. You might post this question in the Exchange group
giving this scenario. I'm sure you can overcome these questions, you will be
much better off by getting everything working with a valid DNS domain name.

This is the link for downloading the ADMT and it has many links for using
the tool.
