Hi,

I have just been testing out the domain rename functionallity using RENDOM in a 2008 R2 test environment. It has all finished successfully, but I have noticed, as written in the documentation that it does not change the DNS suffix in the full computer name. So my question is, is this something I need to change manually or is there extra steps I am missing. As I mentioned before, this is only in a test environment at the moment so there is no worry about breaking anything.

Thanks, and have a great day :)

You have to change the DNS suffix manually on each DC.

(I called the domain controller "DC01" in the example)

1. Add the suffix: netdom computername dc01.olddomain.com /add:dc01.newdomain.local

2. Change the primary DNS suffix: netdom computername dc01.olddomain.com /makeprimary dc01.newdomain.local

3. Reboot the DC.

4. Remove the old DNS suffix: netdom computername dc01.newdomain.local /remove:dc01.olddomain.com

Thank you very much, worked great :)

I know I should probably add another question for this, but do I need to manually join computers to the new domain, or should that happen automatically, or is there another command or somehting I can do?

Thanks

You don't have to rejoin domain members, but you'll have to get them booted twice before you run "rendom /cleanup".

If you have some members that have not been re-booted  twice before you run "rendom /cleanup", you'll have to rejoin them to the domain.

Ok, I remember seeing that in another of the articles I read, but it was not explained as well as well as that, but is the command "rendom /cleanup" the same as "rendom /clean" ?
