Modify Routing for a Subordinate Name Suffix

  • Article

Applies To: Windows Server 2008, Windows Server 2008 R2

You can change the routing status (enable or disable) of a name suffix that is subordinate to the name of a forest. For example, if the wingtiptoys.com forest trusts the fabrikam.com forest and the fabrikam.com forest includes a child domain sales.fabrikam.com, you can enable or disable routing specifically for the child domain name suffix. You can use this procedure to modify routing of an existing subordinate name suffix by using Active Directory Domains and Trusts. You can also use the Netdom command-line tool. For more information about how to use the Netdom command-line tool to modify name suffix routing settings, see Netdom Overview (https://go.microsoft.com/fwlink/?LinkId=111537).

Membership in Domain Admins in the forest root domain or Enterprise Admins in Active Directory Domain Services (AD DS), or equivalent, is the minimum required to complete these procedures. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (https://go.microsoft.com/fwlink/?LinkId=83477).

  2. In the console tree, right-click the forest root domain node for the forest trust that you want to administer, and then click Properties.

  3. On the Trusts tab, under either **Domains trusted by this domain (outgoing trusts)**or Domains that trust this domain (incoming trusts), click the forest trust that you want to administer, and then click Properties.

  4. On the Name Suffix Routing tab, under Name suffixes in the x.x forest, click the forest suffix whose subordinate name suffix you want to modify for routing, and then click Edit.
