Remove a Trust

Updated: March 1, 2012

Applies To: Windows Server 2008, Windows Server 2008 R2, Windows Server 2012

You can use the Active Directory Domains and Trust snap-in to remove trusts.

Membership in Domain Admins or Enterprise Admins , or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at http://go.microsoft.com/fwlink/?LinkId=83477.

Removing a trust

To remove a trust using the Windows interface

  1. Open Active Directory Domains and Trusts. To open Active Directory Domains and Trusts, click Start , click Administrative Tools , and then click Active Directory Domains and Trusts .

    To open Active Directory Domains and Trusts in Windows Server® 2012, click Start , type domain.msc .

  2. In the console tree, right-click the domain that contains the trust that you want to remove, 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 trust to be removed, and then click Remove .

  4. Do one of the following, and then click OK :

    • Click No, remove the trust from the local domain only .

      If you select 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 select this option, you must type a user account and password with administrative credentials for the reciprocal domain.

Additional considerations

  • To perform this procedure, you must be a member of the Domain Admins group or the Enterprise Admins group in Active Directory Domain Services (AD DS), or you must have been delegated the appropriate authority. As a security best practice, consider using Run as to perform this procedure. For more information, search for "using run as" in Help and Support.

  • It is not possible to revoke the default two-way, transitive trusts between domains in a forest. It is possible to delete explicitly created shortcut trusts.
