How to rename and change IP address of Windows 2008 AD Domain?

This is using upgraded Windows 2008 AD Domain. It was being upgraded from Windows 2003 months ago. This is only one DC. Due to some production requirements, I have to change the IP address of the DC, and rename the domain name from abc.com to def.com. Can I do it?

What would be the impact to my existing client workstations? Do they have to disjoin and re-join domain? How about file share permissions? I heard that you have to reboot each workstation twice in order to make use of the renamed domain, is that true and how?

Few doubts here:

      1. Do I have to manually create the new domain dns zone on my dns server first?
      2. How about user profile, does the user would having new user profile after the domain renamed?

there is no any risk in changing IP or name of a DC, but for a safe practice create an additional DC as a backup

you have to
you only have to point clients to new IP   as their Preferred DNS

and about domain rename dont do it if you have exchange pre SP1 it can lead to complications.
otherwise you can rename your domain your domain will be out of service for some time and client only have to reboot twice(no need to rejoin) and if you have NT clients then it is necessary to unjoin and rejoin them

Here is a walkthrough for 2003. No difference with a 2008 domain.

You don't have to do anything with the roaming profiles.

How about only changing the netbios name of the domain?

snusgubbenCommented:
Same thing.

You can change:

- DNS and NetBIOS name
- only DNS name
- only NetBIOS name

This is a single-domain forest, with only 1 w2k8 dc. No exchange and none of the application tied to domain. If I only want to change the netbios name of the domain, let's say abc to xyz, how to do it step-by-step?

(almost) Same steps as a full domain rename, but you don't need to create a new Forward lookup zone.

Other things I can think of is that you don't need to change the DNS suffix

You edit the "domainlist.xml" to reflect the new NetBIOS name and leave the DNS name as it is.

The steps are not different for a 2008 domain. They are all the same.

I don't think you have to download the rendom.exe tool, as if I remember correct the tools are already on a 2008 server.

yes balack the link i attached can also be useful for even 2008 but remember you have to do more tasks than me cause i tested this on a single DC.

the default location for rendom in 2008 is here %windir%\system32\rendom.exe.
