Verify a Trust

  • Artikel

Applies To: Windows Server 2008

You can use Active Directory Domains and Trusts to verify whether the newly added shortcut, external, and forest trusts were created successfully.

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 Local and Domain Default Groups (https://go.microsoft.com/fwlink/?LinkId=83477).

Verifying a trust

  • Using the Windows interface

  • Using a command line

To verify 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.

  2. In the console tree, right-click the domain that contains the trust that you want to verify, 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 verified, and then click Properties.

  4. Click Validate.

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

    • Click No, do not validate the incoming trust.

      If you select this option, we recommend that you repeat this procedure for the reciprocal domain.

    • Click Yes, validate the incoming trust.

      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.

  • You can verify trusts for shortcut trusts, external trusts, and forest trusts, but not realm trusts.
