Change IP address of Primary Domain Controllers


We are planning on changing the IP address of our two Domain Controllers.  These both run DNS and WINS for the domain, and the FSMO Roles are split between the two servers.

Are there any best practices to follow and should we be aware of anything critical when performing this?

If you are able to, then overlap the ip addresses until propagation completes
if the ip's are of the same subnet, then use the new range as the gateway and allow incoming traffic on the old.
try checking against far away dns servers before removing the current ip's

As long a you do not lose resolution, you should be ok

If you just have the one site then it is as straight forward as changing the IP's and restarting net logon services (or better rebooting the servers)


These will no doubt be your DNS servers aswell? so you would have to change your DHCP scope to reflect the changes and get all clients to reboot or /release /renew etc so they get the updated DNS server ip's. Not to mention any other servers that have these IP's set as static DNS entries.
