VBscript query to get group member information for multiple domains in a forest.

I am updating a script that we have that goes into AD and extracts all email enabled users, groups and contacts and dumps them to a CSV file.  I am having an issue now because we have an additional child domain in our forrest.  Need to be able to run this script and create one CSV file that contains the forest users and distribution groups and contacts.  

The problem is that when I do a query of the GC i only get the members of groups not in the domain.  To get the groups of the domain I am in I can query LDAP instead but then I don't get the other domain's group members.  I am lookin for a solution that is not going to double the code.

'Attach to Active Directory
set objRoot = GetObject("LDAP://rootDSE")
strDNS = objRoot.Get("defaultNamingContext")
strRootDNS = objRoot.Get("rootDomainNamingContext")
set objConnection = CreateObject("ADODB.Connection")
ObjConnection.Open "Provider=ADsDSOObject;"
set objCommand = CreateObject("ADODB:Command")
objCommand.ActiveConnection = objConnection
objCommand.Properties ("Page Size")= 500      	'500 results at a time
objCommand.Properties ("Cache Results")= False  'Reduce Client mem Consumption
'=====Query Global Catalog======
objCommand.CommandText = "<GC://" & strRootDNS &">;" & _
"(&(objectCategory=group)(objectClass=group));" & _
"name,cn,SAMAccountName,mail,givenName,sn,displayName," & _
set objRecordset = objCommand.Execute
inNumGroups = 0
Wscript.Echo ("Pre-Processing (objectCatagory=Group)(objectClass=Group) Data...")
'===Write information to Export File===
While Not objRecordSet.EOF
    'working code
 arrMember = objRecordSet.Fields("member")
For each strMember in arrMember

Place the constanst


at the start of your script.

Then alter this section of your code:
set objCommand = CreateObject("ADODB:Command")
objCommand.ActiveConnection = objConnection

to read:

set objCommand = CreateObject("ADODB:Command")
objCommand.ActiveConnection = objConnection
objCommand.Properties("Searchscope") = ADS_SCOPE_SUBTREE
My script first builds an array of domain names.  Next, the script will loop through each domain and continue executing code.

I changed your code a little to check to see if the group has members and also added "primaryGroupID" as a field to query.  It is important to note that a users primary group is listed at the user level and they are not recorded as members of that particular group in the traditional sense.  Take for example the Domain Users group.  If you run the code as is, the domain users group will not contain everyone you would expect.  Because the primary group is held within the user accounts, it is foreseeable that you will also have to pull user data as well.

In the end, I imagine doubling the code is entirely possible.
'Flush out all domain names found in AD and add them to arrDomainNames
set objRootDSE   = GetObject("LDAP://RootDSE")
strBase          = "<LDAP://cn=Partitions," & objRootDSE.Get("ConfigurationNamingContext") & ">;"
strFilter        = "(&(objectcategory=crossRef)(systemFlags=3));"
strAttrs         = "name,trustParent,nCName,dnsRoot,distinguishedName;"
strScope         = "onelevel"
set objConn      = CreateObject("ADODB.Connection")
objConn.Provider = "ADsDSOObject"
objConn.Open "Active Directory Provider"
set objRS = objConn.Execute(strBase & strFilter & strAttrs & strScope)
