Hi Graham,

I would suggest to move DNS to the new server.

But in the meantime, are there any errors showing up in the event viewer of any of the DCs?

Are other machines still able to register?

I assume that the 2000 DNS server is the only IP on the 2008 machines.

ace, thanks for the post back. i do recall corresponding with you many
years back on dns, so i hope you are well !

i agree with suggestion to move DNS to the newer w2k8 - this will be
a strategic goal, but need to consider an interim step of w2k8 domain
controllers (not running DNS) configured with w2k dns server.

to put this in to context, we are doing the testing of a forest
upgrade to w2k8 from w2k, so adprep etc , dcpromo etc which all
(apparently) has gone ok

dns functionality (from w2k8 domain member to w2k) would seem to be
ok, as the tasks of domain join, dcpromo completes ok., such that we
can access the directory from ADUC on w2k8.

we run dcdiag by way of procedure to verify a DC installation., which
leads us to the apparently failed dns, confirmed by review of the
[missinfg] DNS zone data on the w2k DNS server.

there are no event log entries that look relevant

wasnt' quite sure what you meant by the last qu. ?
for info, the w2k8 server has the ip addresses of the 2 x w2k dns
servers in its IP config if that is what u mean

initial thoughts that i consider are perhaps that the w2k8 dc is
trying to register records (ip6 ??) that the w2k is simply rejecting,
and causing failure of other zone data.

all other w2k8 configuration could be assumed to be default (we have
not yet disabled IP6)

Thanks

Graham,

You can disable IPv6, just in case it is the problem, but I don't think it is. Here are the instructions. Try a manual registration afterwards:
ipconfig /registerdns
net stop netlogon
net start netlogon

Disabling IPv6
=======================
With errors regarding to Outlook Anywhere, such as to fix an NSPI issue on port 6004, Disable IPv6 in registry on the Exchange server.
Or to or to simply disable IPv6 on any server:

Uncheck IPv6 in NIC properties
Uncheck the two LinkLayer Topology Discovery components
Then follow the registry changes procedure below to completely disable IPv6.

1. Navigate to:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip6\Parameters]
2. In the details pane, click New, and then click DWORD (32-bit) Value.
3. Type in DisabledComponents , and then press ENTER.
4. Double-click DisabledComponents,
5. Type ff in Hexadecimal.
6. So it should like this when completed:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip6\Parameters]
"DisabledComponents"=dword:000000ff
