2003 Active Directory Domain Controller - Change IP address of the DC

Medium Priority

Last Modified: 2012-05-07
Runnning 2003 server R2 with SP2 as a Domain Controller in a 2003 AD network. There are other DC's on the same network.
It is intended to put the DC on a different network hence requiring to change the IP address of the server.
Will this effect anything in the AD/DNS side of the setup. It will required to put the server link on a "slow link" so that AD updates are not as requent.
Just worried changing the IP address may effect things in Active Directory.

Excellent, thanks for the confirmation of that nice to know. Just didnt want to change the IP address and things stop working. Have you ever done this and changed it using "sites and services" and putting it over a "slow link"

not recently - but I'm sitting in a room with another network admin who says that when you select the slow link and lower the replications it doesn't make any difference whatsoever.  you may get a few machines to begin with who want that DC and can't immediately find it, but running the command gpupdate /force and then rebooting with make the machine "shout" for a new DC on boot and one of the more readily available DC's will reply and off you go :)

Thats a bit worrying , as I am having to built a DR site and intend to put the DC on this site an donly want it to replicate now and again . I have read if you make the link priority lower it will not repliate as frequent or take as much bandwidth up over the link.
That's true.  Replication will happen less frequently and at a slower rate, but this isn't usually a problem.

This will only be a temporary problem on your current site where machines still want that DC - but this will only be a problem for a matter of hours or days at most.

As long as you set your replication times properly then all will be OK.  I would suggest making sure you get at least 2 overnight replications, one just after logon in the morning, a couple over lunch time and one or two in the afternoon - all will be absolutely fine
