Change the IP address of a Domain Controller

Change the IP address of a Domain Controller

1.       Change IP on server.

2.       Register DNS on server with changed IP address.  Ipconfig /registerdns 

3.       DNS servers on each server NIC. 

4.       Dcdiag /fix 

5.       Verify\update DNS records for servers. 

6.       Update group policies, printer mappings, file share mappings, and login scripts to new (IP if you are using IPs for some reason) 

7.       DHCP server\scope option DNS settings. 

8.       (Optional) Flush DNS on all DCs. Ipconfig /flushdns

9.       After some time check the status of replication if needed.  Repadmin /showrepl

If there are multiple DCs, I use:

nslookup hostNameorIPaddress DNSservertoquery

nslookup [this name or address] [on this name or address]

nslookup DC1 DC1

nslookup DC1 DC2

nslookup DC2 DC1

nslookup DC2 DC2

make sure that all servers use each other for their own DNS on the NIC. Primary DNS (local IP, or 127.0.0.1), then no particular order for the rest.
