Rename Domain Name

Posted on 2004-09-20

Ok, I did something stupid. I set up a new Windows 2003 Small Business Server on Friday, and somehow managed to mis-spell (mis-type) the company name for the domain name. Now, every where I look in the system, the domain name is missing an 'i'. I have already setup Exchange (which is working fine), and transferred all of the data, and joined all 27 computers to the new domain. So, I did some research and found the 'rendom.exe' tool, and wanted to know, is this what I use? Has anyone had to use it? What can I expect from it? Is there a better way to do this? Should I even bother? The only reason that I noticed it, is in the Global Address List in Outlook, it automatically creates a group, and that group is mis-spelled. Ouch, I feel dumb!
I have already changed the domain dns suffix, but that doesn't change the domain name.

Sure looks like the tool you need to use. Do keep in mind that if you change the DNS and specially the Netbios domain name, you will need to readd all computers to the domain (because the domain name changed). Before doing this, i would delete all computer accounts within the AD. just to be on the safe site...

I don't plan changing the Netbios Name. That is how I added all of the computers to the domain. Will I still need to re-join all of the computers to the domain again?
Have you used the tool before?

I hate to be the bearer of bad news :(  Renaming a domain in SBS is not possible. Your only options are to accept the typo as the domain name or reinstall and create a new domain:

Hope this helps :S
