change ip address on w2k domain controller

[Yonkey]

Hi,

We have created a segment in our corporate network for all the servers. So I
need to change the ip address of my domain controller to new ip address
which is belong to our server farm subnet. I have a DNS and WINS installed
on the domain controller. Please advise as I'm not sure what steps should I
take. Thanks

For the IP, change the IP. If this server is a GC, check in DNS under the
_msdcs.gc zone and delete the old IP for this GC.
Delete the PTR record in your reverse zone.

Then in a cmd prompt:

ipconfig /registerdns
net start netlogon
net stop netlogon

Then confirm under your zone that these all changed to the new address:
If GC, check the zone I mentioned above.
Check the (same as parent) A record IP to make sure that changed.
Check the A record for the host name as well.

For WINS, the easiest way I've found is to disable the NIC and re-enable it.
It should register its new address in WINS. Check WINS to confirm.

You can also just restart the system, but still double check everything.

Thanks for your reply, what happen if I upgrade to Windows 2003 and then
only I change the ip address ? will it be a different method to change the
IP once I have upgraded to Windows 2003 ?

Hi Ace,

I just cant find " _msdcs.gc zone and delete the old IP for this GC.
" as you said after changing the ip address.

So it is a GC? Ok, try this...

Under your domain.com zone (or whatever your zone is called) you will see:
_msdcs
_sites
_tcp
_udp


Double click the _msdcs folder. Under it you will see a folder like this:
_gc

Double click that. To the right you will see an IP address. Check that.

Everything works fine now, after I found i've misconfigured the time zone.
Thanks alot Ace !

Thanks Ace,

It works but I think I still miss something here. After changing IP, I try
to create a 2nd domain controller but failed. I have sync the time between
the server that I want to add as a 2nd DC with 1st DC but failed. I attached
the error msg here and maybe you have an idea on what to looking for. Thanks
