I sucessfully set up a test Windows 2000 domain with Active Directory.

The current Active Directory setup is as follows:

Active Directory Users and Computers
-hcompany.com
 +Builtin
 +Company
 +Domain Controllers
 +Foreign Security Principals
 +Users

The domain name is hcompany.com

I want to rename this domain from hcompany.com to h.company.com

This is a test domain and is not in production.

How do I do this ?

Thanks,
st

The short answer is you can't.

Domain rename is not supported in Windows2000 - only in 2003 and even then its not something to be done lightly.

That said as this is a test domain I suppose there is no harm in trying but you will have to have a mixed mode domain with an NT server to stand a chance - and you need to demote and re-promote the 2000 DCs in the process - its very messy. It would be simpler to start again.

see http://www.shijaz.com/windows/domain_rename_2k.htm

good luck (you will need it)

Under Windows 2000, there is no supported process to rename a domain. There is one workaround for mixed-mode domains in which you revert the domain and any of its child domains back to Windows NT domains. This can be done by demoting all Windows 2000 domain controllers and leaving the Windows NT domain controllers in place, or simply by rebuilding all of the 2000 DCs. You could then reintroduce Windows 2000 domain controllers and use the new domain name when setting up Active Directory. The process is not very clean and probably won't be suitable for most situations, but you can find out more about it in MS KB 292541.

A domain rename procedure is supported if a forest is running all Windows Server 2003 domain controllers and is at the Windows Server 2003 forest functional level. Microsoft provides a rename tool (rendom.exe) and detailed white paper describing the process at the following location: http://www.microsoft.com/windowsserver2003/downloads/domainrename.mspx.

Although the domain rename procedure is greatly simplified in Windows Server 2003, we highly recommend reading the entire white paper before attempting the procedure, as well as attempting the procedure in a test lab before performing it against a production environment.
