Our company just changed names so we would like to change
our domain name to match. I've heard that when you
upgrade win2k to win2k3 you can change the domain. Is
this possible?

Click to expand...
If you don't have Exchange or Certificate Services and no 3rd Party apps
which will mind you are able to use the Domain Rename Feature.

There are other options as well, like building another domain tree in the
same forest and moving all the ressources ... depending on your szenario.
Domain Rename is still a very serious issue and needs a _lot_ of testing.

Yes, Windows Server 2003 does have this ability. Here are a few considerations before you go this route.

- All domain controllers must be running Windows 2003.

- The Windows 2003 forest functionality level must be raised to Windows
.NET Server 2003. To determine the mode in which the domain is
currently running, expand Active Directory Users and Computers,
right-click the domain name, and then click Properties. The mode
appears in the Domain operation mode dialog box.

- Rendom cannot be used to drop domains from the forest or add domains
to the forest. The number of domains in the forest before and after the
rename/restructure operation must remain the same.

- Rename a domain to use the same name that another domain gave up in a
single forest restructure operation.

- Domain rename operations are not supported in an Active Directory
forest that includes an Exchange 2000 deployment

- The forest will be out of service for a short period of time. Forest
service is interrupted during the time it takes for each domain
controller to perform the directory database updates necessary for the
domain rename and then reboot.

- All domain controllers must either successfully complete the rename
operation or be eliminated from the forest.

- Each member computer joined to a renamed domain must be rebooted
twice after all domain controllers have been updated. Machines running
Windows NT 4.0 will need to unjoin and then rejoin the renamed domain
instead of rebooting.
