Enumerate objects within Domain Computers?

i want to be able to loop through all of the computers within Domain Computers.  when i run the code listed, it will successfully work for every me-created group (e.g. myTestComputerGroup, etc) but when i run it against, Domain Computers, I get:  "The directory property cannot be found in the cache."  So i ran Active Directory Explorer to see the differences and they are apparently striking.  Normal groups keep a list of their members in an attribute called "member."  However, my Domain Computers group does not have a "member" attribute and from Active Directory Explorer I can even tell what computers are in it (and yes, there are some).  Does anyone know why this is or how I can loop through all of the computers in Domain Computers?  ADUC can obviously do it...  o.O
Option Explicit
Dim strMember, strDNSDomain, strContainer
Dim objGroup, objRootDSE
Dim arrMemberOf
strContainer = "cn=Domain Computers,cn=Users, "
Set objRootDSE = GetObject("LDAP://rootDSE")
strDNSDomain = objRootDSE.Get("defaultNamingContext")
WScript.Echo "LDAP://"& strContainer & strDNSDomain
Set objGroup = GetObject("LDAP://"& strContainer & strDNSDomain)
arrMemberOf = objGroup.GetEx("member")
WScript.Echo "Members of Group " & strContainer
For Each strMember in arrMemberOf
   WScript.echo strMember

Hi There
Unfortunately you cannot loop through "Primary Groups" to get their memberships list (As you already found out)
Every group in AD has a n attribute called PrimaryGroupToken which is given a number. The Builtin Groups, i.e. Domain Users, Domain Computers etc. have a universal number, menaing every AD will be the same number;, of 515 for Domain Computers, 513 for Domain Users etc.
Every Computer (and user) will have a primary group and their primary group attribute called PrimaryGroupID will have a number of (assuming their primary group is Domain Computers - becuase this can be changed) will have a number of 515.
So in order to list all computers in the Domain Computers group you need to search all computer objects with a PrimaryGroupID of 515.
A bit convoluted i know, but that is how its done it seems.
Hope that helps explain the situation for you. In my vbscript I would use ADO to search AD for all objects that has a PrimaryGroupID of 515 as the best way to do this.
To help you get started and build an ADO script with what you need, have a look at this excellent site by Richard Mueller ADO Search Tips
