Hi
I'm currently trying to promote a domain member server to
a second domain controller.
I'm running Win2000 advanced server.

Each time after entering credentials for the domain I'm
try to join it gives an error that the domian could not be
contacted or there may be a DNS lookup problem.
I know DNS is wroking fine, i can ping forward and
reverse, I can do NSlookups. It all work fine.
The IP of the domain controller is lets say 159.140.82.20
there is a management card in the DC on IP 159.140.101.99
which is on a different subent v-lan.
When I do NBTSTAT -c on the DC
it shows the name of the domian 'JRTWED' on IP address
159.140.101.99 so I know this is why it cant'f find the
domain. I've tried a few things including disabling the
managment card but problem still persists.
Is the a registry edit I need to do...?
Please adive most gratefully appreciated
 
You need to configure the DC to stop the management card IP address from
being registered in DNS. This will allow other clients to find the DC. For a
DC that is running a DNS server, there are three tweaks you have to make to
accomplish this. This kb gives you all the details
http://support.microsoft.com/?id=246804

In summary, this is what you need to do:
On the management card TCP\IP properties, untick the 'register this
connections address in DNS' box
Make the registry change that stops the Netlogon service registering the
address
Make the registry change that stops the DNS service registering the address
 
As well as following Simon's great advice, I would also check the binding order and ensure that the NIC is first and the management card second. And also ensure that there's either no default gateway on the management card, or if that is necessary, assign it a higher cost that the default gateway of the NIC. NetBT binds to the first availble adapter, and DNS always uses the adapter with a default gateway -changing the metrics will ensure DNS uses the correct adapter
