Gets the native Active Directory Service Interfaces (ADSI) object.
Assembly: System.DirectoryServices (in System.DirectoryServices.dll)
Use this property to cast the native Active Directory Domain Services object, which implements the IADs interface, when you want to use a COM interface. For more information about the IADs interface, see the topic IADs in the MSDN Library at http://msdn.microsoft.com/library.
This object is for advanced scenarios that cannot be accomplished with the System.DirectoryServices classes alone. To use it, you need to import one of the COM interfaces from the IADs family, then cast this property to that interface.
