Hvordan for jeg netbootGUID (UUID) med LDAP?

Jeg har denne kode og kan godt "få" Name men ikke netbootGUID.

Kode:

Const ADS_SCOPE_SUBTREE = 2
Set objConnection = CreateObject("ADODB.Connection")
Set objCommand =  CreateObject("ADODB.Command")
objConnection.Provider = "ADsDSOObject"
objConnection.Open "Active Directory Provider"
Set objCommand.ActiveConnection = objConnection
objCommand.CommandText = _
    "Select Name, netbootGUID from 'LDAP://DC=domain,DC=dk'" _
      & " where objectClass='computer'  " 
objCommand.Properties("Page Size") = 6000
objCommand.Properties("Timeout") = 30
objCommand.Properties("Searchscope") = ADS_SCOPE_SUBTREE
objCommand.Properties("Cache Results") = False
Set objRecordSet = objCommand.Execute
objRecordSet.MoveFirst

Do Until objRecordSet.EOF
Wscript.Echo "Computer Name: " & objRecordSet.Fields("Name").Value
Wscript.Echo "netbootGUID: " & objRecordSet.Fields("netbootGUID").Value

    objRecordSet.MoveNext
Loop
