Is this Google Groups or Google Groups for Business? Google Groups for Business is the core service, but Google Groups is a non-core service and some schools do not allow the non-core services.
That could explain part of your problem?

Subject: Joining Google Groups
Hi - The librarian at our school wants to join the google group here:
But when signed into our school domain, we can't get there, join, etc. What am I not understanding? (Well, there's a lot I don't understand, but what about Google Groups don't I understand?)
