Remarks

A directory context must be created before accessing the methods and properties of a System.DirectoryServices.ActiveDirectory directory object such as a domain or forest.

When creating a directory context, the process' current credentials or alternate credentials can be applied to that context by using the appropriate constructor. These credentials determine the permissions that are in effect when the program accesses directory objects. Because Active Directory Domain Services objects might be protected against retrieval or modification by non-administrative users, the use of alternate credentials with permission to access the target objects is sometimes necessary for proper program functionality.

The following table contains a list of the target types that are allowed and a description of the format of the target string.

Target type	DirectoryContextType member	Target name format
Domain Controller	DirectoryServer	The DNS name of the domain controller.
AD LDS Instance	DirectoryServer	The DNS name of the AD LDS server and the LDAP port number, for example, ad_lds_instance.fabrikam.com:389.
Domain	Domain	The DNS name of the domain, for example, sales.corp.fabrikam.com.
Forest	Forest	The DNS name of the forest, for example, corp.fabrikam.com.
Application Partition	ApplicationPartition	The DNS name of the application partition.
AD LDS Configuration Set	ConfigurationSet	One of the keywords that is associated with the service connection point registered by AD LDS instances for the configuration set.
