Namespace: System.DirectoryServices.ActiveDirectory
Assembly: System.DirectoryServices (in system.directoryservices.dll)

public void CreateLocalSideOfTrustRelationship (
	string targetDomainName,
	TrustDirection direction,
	string trustPassword
public void CreateLocalSideOfTrustRelationship (
	String targetDomainName, 
	TrustDirection direction, 
	String trustPassword
public function CreateLocalSideOfTrustRelationship (
	targetDomainName : String, 
	direction : TrustDirection, 
	trustPassword : String
Not applicable.



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


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


The password for the trust. See remarks below.

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.


targetDomainName or trustPassword is empty.


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


direction is not a valid TrustDirection value.


The object has been disposed.


The specified account does not have permission to perform this operation.

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 Domain.CreateTrustRelationship method.
