Changing IP address on a domain controller. Need help.

[wchull]

Hello,

We have a situation that we need help with.

We have an office where we have to change the IP address on every machine to a completely new IP address scheme. The office currently has two Windows 2000 domain controllers running Active Directory, DHCP and DNS on each machine and the IP address on these two machines must change as well. Note that there are other Windows 2000 domain controllers in other offices located in other states who are set up with Active Directory, DHCP and DNS that will stay "AS IS". All of these active directory domain controllers "talk" to each other and the zones on these servers are all active directory integrated.

I am concerned that we don't know all the steps needed to change the IP addresses on the two domain controllers and get everything working correctly in the office much less getting all the domain controllers in all offices "talking" to each other after the IP address change.

If anyone can provide us with any information about how to correctly change the IP addresses on these two domain controllers we would very much appreciate the help.

Thanks,

I don't know some MS kb discussing about this. somebody make a post in

[see below]
I don't test it but it should be good to add
at the end of the process the command : nbtstat -R and nbtstat -RR in order to refresh on the network card and in wins even if the net stop/start netlogon do it by design.

Changing the IP address on a domain controller
Eileen Crabtree
01 Sep 2003
Select: Start -> Settings -> Network and Dial Up Connections
Select: Your Local Area Connection
Select: Internet Connections (TCP/IP) Properties
Change: Your IP Address and Subnet Mask and Gateway
Change: Preferred DNS server's address to the new server address
Select: OK -> OK -> Close

Your server's address is now changed.

Select: Start -> Programs -> Administrative Tools -> DNS

Double click Forward Look Up Zones. Then double click your server name.

Delete: Your type A records

Reset your information in your SOA and NS records and exit DNS. Now drop down to an MS-DOS prompt and type the following:

ipconfig /flushdns Enter
Net Stop DNS Enter
Net Start DNS Enter
Net Stop Netlogon Enter
Net Start Netlogon Enter

ipconfig /registerdns Enter

You can now go back to DNS and make sure the records were all created and they should have changed the address to the correct address on their own.

Now run NSLookup from an MS-DOS prompt and see if all is resolved OK or not. It the names and IP addresses all resolve correctly, you're all set. If not, then go back to NSLookup and type set root=servername (the name of your DNS domain) and hit Enter. When the prompt returns, type exit to exit out of NSLookup. When you type NSLookup, it should resolve the name correctly.
