To remove a trust

Open Active Directory Domains and Trusts.
In the console tree, right-click the domain that contains the trust you want to remove, and then click Properties.
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.
Do one of the following, and then click OK:
- Click No, remove the trust from the local domain only.
  
  If you choose this option, it is recommended 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 choose this option, you must type a user account and password with administrative credentials for the reciprocal domain.
