are maintained until you remove the old computer name so that there is no interruption in the

ability of clients to locate or authenticate to the renamed domain controller, except when the

domain controller is restarted.

Note To perform this procedure, you must be a member of the Domain Admins group or the

Enterprise Admins group in Active Directory, or you must have been delegated the appropriate

authority. As a security best practice, consider using Run as to perform this procedure.

To open a command prompt, click Start, point to All Programs, point to Accessories, and then

click Command Prompt.

This command-line method requires Netdom, a tool installed with the Windows Support Tools in

the Support\Tools folder on the Windows CD-ROM.

If the domain controller belongs to a group with a Group Policy enabled on its primary DNS suffix,

the string specified in the Group Policy is used as the primary DNS suffix. The local setting is used

only if the Group Policy is disabled or unspecified.

By default, the primary DNS suffix portion of a computer's FQDN is the same as the name of the

Active Directory domain to which the computer is joined. To allow different primary DNS suffixes,

a domain administrator can create a restricted list of allowed suffixes by creating the msDS-

AllowedDNSSuffixes attribute in the domain object container. This attribute is managed by the

domain administrator using Active Directory Service Interfaces (ADSI) or LDAP.

Domain controller locator (Locator) DNS resource records are registered by the domain controller

after the renamed domain controller has been restarted. The records that are registered are

available on the domain controller in the systemroot\System32\Config\Netlogon.dns file.

To enumerate the names with which the computer is currently configured, at a command prompt,

type the following:

netdom computername

netdom computernamenetdom computername

netdom computername ComputerName /enumerate:

/enumerate:/enumerate:

/enumerate:{AlternateNames | PrimaryName |

AllNames}

You can also specify a parameter that uses administrator credentials required to modify the

computer account in Active Directory. If this parameter is not specified, Netdom uses the

credentials of the user currently logged on. For more information, see the Netdom command-line

help.

If you rename a domain controller through the System Properties dialog box instead of using the

Netdom tool, DNS and Active Directory replication latency may delay the ability of clients to locate

or authenticate to the renamed domain controller. The length of this latency depends on your

network design and the replication topology of your organization.

The Next Remaining BDC

The BDC called HGFPDC is upgraded next much like the other two domain controllers. Now there

are three domain controllers at the Los Angeles location, but too few employees to justify

maintaining them. The team wants to reduce the number of domain controllers and decides that

PGFPDC will be demoted to a member server.
