I want to change my Domain name

I would like to change the domain name on a mixed 2003/2008 environment. There is also Exchange Server 2003 on the SBS2003 box. The other domain controller is Server 2008 R2. Does anybody have a proven method of doing this? I've seen some articles but I'm hesitant to try. Too scary. What happens to the workstations that are joined to the domain? Do they automatically recognize the domain name change? I need step by step instructions please.

With exchange in the mix, put simply, it cannot be done. The only thing you can do is build a new domain and migrate settings, users, groups, ACLs, export and import mailboxes, etc. You'll have to decide of the effort is justified.

He might be able to with Exchange 2003, KB here doesn't list that version    http://support.microsoft.com/kb/300684

There are blogs with steps like this one http://www.msexchange.org/articles-tutorials/exchange-server-2003/migration-deployment/Domain-Rename.html

I personally haven't tried with exchange 2003 and suggest you test test test before trying anything in production.

Thanks

Sorry, should have been more specific. You can't run rendom when exchange is on a domain controller, such as SBS. Similarly, even running dcpromo to promote or demote a machine that already has exchange breaks things.

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

That makes sense.
The only reason I want to rename it is to shorten it so that the sharepoint users don't have to type the whole thing when logging in. Is it possible to add another domain on the Server 2008 R2 and then add a trust relationship (or something like that).
The current domain is xxxincorporated.com and I want users to be able to use xxx.com
Does the SBS2003 cause an issue with adding a second domain?

Cliff GaliherCommented:
Yes, SBS has issues with that. No trusts.

But your AD domain name has nothing to do with web domain names. If you want another name for sharepoint, a simple CName DNS record and appropriate name in the SSL certificate will work fine.

If your only concern is getting a shorter domain name, why not just create a DNS record to forward xxx.com to xxxincorporated.com?

It would achieve the same thing without the trouble of having to worry about completely renaming your entire domain.

I'm sorry, I guess i wasn't clear. The issue is at the log in prompt for sharepoint. It seems that the user log in must be in the form domain\user. I need domain to be shorter.

Experts told you that what you want to do cannot be done. As such, their answers were accurate and should be accepted.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why
