Domain.CreateLocalSideOfTrustRelationship Method

Creates the local side of a trust relationship with the specified domain.

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

public void CreateLocalSideOfTrustRelationship(
	string targetDomainName,
	TrustDirection direction,
	string trustPassword


Type: System.String
The DNS name of the domain that the trust is created with.
Type: System.DirectoryServices.ActiveDirectory.TrustDirection
One of the TrustDirection members that determines the direction of the trust, relative to this domain.
Type: System.String
The password for the trust. See remarks below.


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 null.


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.
