' Sample to enumerate sites and servers in an Exchange Organization
' using ADSi objects

   Option Explicit

   Sub Main()

   Dim objOrg As IADsContainer
   Dim objOU As IADsContainer
   Dim objConfig As IADsContainer
   Dim objServers As IADsContainer
   Dim obj As IADs

   ' Replace "Server" with the name of any Exchange 5.5 server in one of
   ' the connected sites you want to enumerate.
   Set objOrg = GetObject("LDAP://Server")
   Debug.Print objOrg.Name

   ' filter passes organizationalUnit and any classes derived from it
   ' such as View-Root
   objOrg.Filter = Array("organizationalUnit")
   For Each objOU In objOrg

    With objOU
    ' Test that the most derived class is organizationalUnit
    If objOU.Class = "organizationalUnit" Then
        Debug.Print "Site: " + .Name
        objOU.Filter = Array("Container")
        For Each objConfig In objOU
            With objConfig
            ' Test for cn=Configuration (root container)
            If .Name = "cn=Configuration" Then
                ' In case configuration might have non-containers
                .Filter = Array("Container")
                For Each objServers In objConfig
                    With objServers
                    ' Test for cn=Servers inside of Configuration container
                    If .Name = "cn=Servers" Then
                        .Filter = Array("Computer")
                        For Each obj In objServers
                            With obj
                            Debug.Print Chr(9) & "Server: " & .Name
                            Debug.Print Chr(9) & "ADsPath: "; .ADsPath
                            End With
                        Next obj
                    End If
                    End With
                Next objServers
            End If
            End With
        Next objConfig
    End If
    End With

   Next objOU
   Debug.Print "End Enumeration"
