The DNS name of the forest that the trust is created with.


One of the TrustDirection members that determines the direction of the trust, relative to this forest.


The password for the trust. See the Remarks section for more information.

Exception typeCondition


The trust relationship already exists.


A call to the underlying directory service resulted in an error.


The target server is either busy or unavailable.


targetForest name or trustPassword string is empty.


targetForest or trustPassword is a null reference (Nothing in Visual Basic).


direction is not a valid TrustDirection value.


The object has been disposed.

This method creates one side of a trust relationship. The trust is not established until both sides of the trust have been created.

The trustPassword parameter associates a password with the created trust. When the other side of the trust is created, the same password is provided and the two local trusts are then bound to each other.

To programmatically create both sides of a trust relationship in a single method call, use the Forest.CreateTrustRelationship method.
