in w2k ad it is not possible to rename the domain name.

there are 2 possibilities though!
(1) demote the DC, promote the DC using a new domain name. everything
(users, groups, computers, permissions, access to resources) is lost

(2) create a new parallel forest/domain with the new name and migrate
everything (users, groups, computers, permissions, access to resources) from
the old domain to the new domain. For this to work both the DNS domain name
and the NetBIOS domain name must be different between old and new!

as you can see the best option is (2)!

Migration high level steps are:
* Make sure the AD has been configured (sites, subnets, replication, OUs,
GPOs, delegations, DNS, WINS, DHCP, etc.)
* Setup name resolution (WINS or DNS) between source and target
domain/forest
* Setup trusts (if an external trust is configured and sidhistory is used,
disable sid filtering)
* Install and configure migration tooling
* Migrate groups, user accounts with passwords and group memberships (with
sidhistory)
* Migrate clients from the source domain to the target domain, translate
security on the client, and translate profiles (at this moment users start
logging on with their new AD account on the migrated clients that have been
migrated previously to the w2k3 domain)
* Migrate mailboxes if needed
* Migrate servers to the new domain or migrate data to new servers
* Translate security (Re-ACL) of the data/resources from source security
principals to target security principals (replace the security descriptors
from the old domain with the security descriptors from the new domain )
* Cleanup temporary configurations
* Cleanup sidhistory (recommended!). sIDHistory is used to access resources
while those resources still have security descriptors from the old domain.
As soon as all data (file, folders, mailboxes, etc.) have been re-ACL-ed
sIDHistory can be cleaned. Sidhistory should only be used temporary for
migration purposes!
* Remove trusts
* Decommission old domain(s)


For more info on migrating to an AD domain also see:

ADMTv3 has been out for a while, so be sure to use that version.

to migrate DHCP:
MS-KBQ325473_How to move a DHCP database from a computer that is running
Windows NT Server 4.0, Windows 2000, or Windows Server 2003 to a computer
that is running Windows Server 2003
MS-KBQ885687_You receive an error message when you try to move a DHCP
database by using Netsh.exe on Windows Server 2003

to migrate GPOs use GPMC scripts
