Remove a Manually Created Trust
Applies To: Windows Server 2008, Windows Server 2008 R2
It is possible to remove manually created shortcut trusts, external trusts, realm trusts, or forest trusts. It is not possible to remove default, two-way, transitive trusts between domains in a forest. It is particularly important to verify that you successfully remove trusts if you are planning to re-create them.
You can use this procedure to remove a manually created trust by using the New Trust Wizard in the Active Directory Domains and Trusts snap-in or by using the Netdom command-line tool. For more information about the Netdom command-line tool, see Netdom Overview (http://go.microsoft.com/fwlink/?LinkId=111537).
Membership in Domain Admins 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 (http://go.microsoft.com/fwlink/?LinkId=83477).
Removing a manually created trust
Using the Windows interface
Using a command prompt
To remove a manually created trust using the Windows interface
Open Active Directory Domains and Trusts.
In the console tree, right-click the domain that contains the trust that you want to remove, and then click Properties.
Click the Trusts tab.
In either Domains trusted by this domain (outgoing trusts) or Domains that trust this domain (incoming trusts), click the trust to be removed, and then click Remove.
Do one of the following, and then click OK:
Click No, remove the trust from the local domain only.
If you click this option, we recommend that you repeat this procedure for the reciprocal domain.
Click Yes, remove the trust from both the local domain and the other domain.
If you click this option, you must type a user account and password with administrative credentials for the reciprocal domain.
To remove a manually created trust using the command line
Open a Command Prompt as an administrator: On the Start menu, right-click Command Prompt, and then click Run as administrator. If the User Account Control dialog box appears, provide credentials, if required, and then click Continue.
At the command prompt, type the following command, and then press ENTER:
netdom trust <TrustingDomainName> /d:<TrustedDomainName> /remove /UserD:<User> /PasswordD:*
The Domain Name System (DNS) name (or NetBIOS name) of the trusting domain in the trust that is being created.
The DNS name (or NetBIOS name) of the domain that will be trusted in the trust that is being created.
The account name of the user authorized to create the trust.
If you are using Netdom to remove a realm trust, you must add the /force option to the end of the command (after /remove) to remove the trust successfully.
