Removing a trust
When a trust is no longer needed, it can be deleted.
Getting ready
Preferably, you should sign in to the domain controller that is running the Domain Naming Master FSMO role or connect the Active Directory Domains and Trusts console to this specific domain controller.
To find this domain controller, right-click the Active Directory Domains and Trusts node and select Operations Master... from the menu. Alternatively, run the following command from any domain-joined device, member server, or domain controller:
netdom.exe query fsmo
Otherwise, you can use the following line of Windows PowerShell on a domain-joined system that has the Active Directory module for Windows PowerShell installed:
Get-ADForest | Format-List DomainNamingMaster
To remove a shortcut trust, use an account that is a member of the Domain Admins group in the Active Directory domain. To remove other trusts, use an account that is a member of the Enterprise Admins group.
