How do I add users to Groups in AD when the users are in one domain and the goup is in another domain in a VB script?

I am new to scripting LDAP in VB and I am currently spinning my wheels on a particular item.  I've attached the VB script below for reference.  So, here's the situation in a nutshell: I want to add Users from an OU in one domain (DN: qahbank.emogc.net) in our forest (adrootqa.emogc.net) into a Group in another domain (DN: nbitqa.ca) in our forest.

When I run the script while logged in to "qahbank.emogc.net", for example, the OU containing the users can be located via LDAP but it cannot locate the Group that exists in domain "nbitqa.ca".  Conversely, when I run the script while logged in as an Enterprise Admin in "nbitqa.ca", the LDAP query locates the Group but cannot locate the Users in "qahbank.emogc.net".  I'm fairly sure that the "general" LDAP:// or GC:// queries in the script aren't spanning across the domains

So, my question is thus: how can I hard-code or force the two queries to use a specific domain or even Domain Controller so neither of the queries fail or should I specify the separate domains GC's in the opening arguments / strings?  What is the syntax for using specific GC's or domain's in an LDAP query in a VB script?

Apologies for the long-winded message and I hope I managed to convey the gist of this.

Thanks!
