You can use this procedure to rename a domain controller by
using the Netdom command-line tool.
The netdom command updates the service principal name (SPN)
attributes in Active Directory for the computer account and
registers Domain Name System (DNS) resource records for the
new computer name. The SPN value of the computer account
must be replicated to all domain controllers in the domain,
and the DNS resource records for the new computer name must
be distributed to all the authoritative DNS servers for the
domain name. If the updates and registrations have not
occurred prior to removal of the old computer name, some
clients might be unable to locate this computer using the
new name or the old name.
Administrative credentials
To perform this procedure, you must be a member of the
Domain Admins group or the Enterprise Admins group.
To rename a domain controller using Netdom
1.Open a Command Prompt.
2.Type the following command to add the new domain
controller name, and then press ENTER:
netdom computername CurrentComputerName /add:
NewComputerName
3.Type the following command to designate the new name as
the primary computer name, and then press ENTER:
netdom computername CurrentComputerName /makeprimary:
NewComputerName
4.Restart the computer.
5.After the computer restarts, open a Command Prompt.
6.Type the following command to remove the old domain
controller name, and then press ENTER:
netdom computername NewComputerName /remove:
OldComputerName
Use this procedure to update the File Replication service
(FRS) member object after renaming a domain controller.
Administrative Credentials
To perform this procedure, you must be a member of the
Domain Admins group or the Enterprise Admins group.
To update the FRS member object
1.Using Ldp.exe (or ADSI edit), find the computer object of
the renamed domain controller.
2.Do a recursive search for an object of type
nTFRSSubscriber with the computer name of "Domain System
Volume (SYSVOL share)" under the Computer object.
3.The search filter is "(&((cn=Domain System Volume (SYSVOL
share))(objectclass=ntfrssubscriber)))".
4.Find the fRSMemberReference attribute of the object
returned by the search.
5.Find the object whose domain name is in the
fRSMemberReference attribute. This is the Ntfrsmember
object corresponding to this domain controller.
6.Change the computer name of this Ntfrsmember object from
the old name of the domain controller to the new name of
the domain controller.
