list computer names in active directory

[ivan74]

Hi
Ive found following code forlisting all the computers in active directory:
ActiveDirectorySearch1
Displays all computer names in an Active Directory
Written 08/26/02 - John ODonnell - csharpconsulting@hotmail.com
Imports System
Imports System.DirectoryServices
Namespace ActiveDirectorySearch1
Class Class1
Shared Sub Main(ByVal args() As String)
Note : microsoft is the name of my domain for testing purposes.
Dim enTry As DirectoryEnTry = New DirectoryEnTry("LDAP://microsoft")
Dim mySearcher As DirectorySearcher = New DirectorySearcher(enTry)
mySearcher.Filter = ("(objectClass=computer)")
Console.WriteLine("Listing of computers
in the Active Directory")
Console.WriteLine("===========
===========")
Dim resEnt As SearchResult
For Each resEnt In mySearcher.FindAll()
Console.WriteLine(resEnt.GetDirectoryEnTry().Name.ToString())
Next
Console.WriteLine("=========== End of Listing =============")
End Sub
End Class
End Namespace

but there is no system.directoryservices in my visual studio, why?
And how can I list all the computers in active directory?
Please help

You will also need to add a reference to System.DirectoryServices.dll.

Thank you
Sorry Ive found it yesterday.
It works just fine but it brings back ALL the computer names in active directory is it possible to retrieve only computers which are currently in the network?
I would like to fill a combobox with it and have the user select a computer from it.
