ActiveDir CreateUser

The CreateUser sample uses ADSI with the LDAP provider to create a domain account for a user.


Active Dir Credentials

The Credentials sample uses ADSI and the LDAP provider to bind to Active Directory using specified credentials rather than using the default credentials of the logged-on user.


ActiveDIR GCAllUsers

The GCallUsers sample searches the global catalog to enumerate users in an Active Directory forest.


ActiveDir GetDomainMode

The GetDomainmode sample binds to an Active Directory domain partition and reads the ntMixedDomain property to determine the operation mode of the domain.


ActiveDir GetSchemaInfo

The GetSchemaInfo sample uses ADSI to bind to the Active Directory schema container and search for classSchema and/or attributeSchema objects that match a specified query.


ActiveDir PropertyList

The PropertyList sample uses ADSI to bind to Active Directory and enumerate its attributes. The sample Demonstrates use of the IADs, IADsPropertyList, IADsPropertyEntry, and IADsPropertyValue interfaces.



The PropSheetHost Demonstrates how to host the Active Directory Users and Computers MMC snap-in property sheet for an Active Directory object.


ActiveDir QueryUsers Sample

The QueryUsers sample queries an Active Directory domain partition for user objects that match a specified filter.


ActiveDir RootDSE

The RootDSE sample binds to rootDSE of an Active Directory server using the IADs interface and retrieves the defaultNamingContext property, which contains the distinguished name of the domain partition, as well as other naming contexts for the domain.


ActiveDir SID

The SID sample uses ADSI to bind to the local domain partition in Active Directory. It then searches for a specified user object. When it finds the object, the sample retrieves the user’s SID and converts the binary SID to a SID string format.


ADSI ActiveDir User

The User sample binds to a user object in Active Directory and uses the IADsUser interface to retrieve information about the user.


ActiveDir WkGuid Sample
