Im creating a app that will go through all the OU's and look for a
certain user by username. In doing some testing I noticed that its not
filtering everything out exept for user ObjectClass. It seems to be
pulling computers as well. Not sure why this is happening but need to
limit it to just user objects. Here is the code I have.

Imports System
Imports System.DirectoryServices

Namespace ActiveDirectorySearch
    Public Class ADSearch
        Shared Sub main(ByVal strUserName As String)

            Dim DSESearcher As New DirectorySearcher()

            DSESearcher.SearchScope = SearchScope.Subtree
            DSESearcher.Filter = "(objectClass=user)"

            Dim objResults As SearchResult

            For Each objResults In DSESearcher.FindAll()

Console.WriteLine(objResults.GetDirectoryEntry.Properties("samaccountname").Value
& "...." & objResults.GetDirectoryEntry.Path)

            Next
        End Sub
    End Class
End Namespace

Ok after messing around with it I got the filter working correctly, but
it seems to be skipping some OU's. i see it search its parent OU but
some of them. for instance

Domain
-OU-a
--SubOU1
--SubOU2
--SubOU3

It will scan OU-a and all other sub ou's exept Sub2. Any Ideas
