@Brian81
When I execute the query:
select * from sem5.SEM_CLIENT client
inner join sem5.sem_computer computer on computer.COMPUTER_ID=client.COMPUTER_Id
order by client.client_id
I get 102 records returned which is the same number of licenses in use (allegedly) and since we only have a few systems (confirmed with a query) I suspect there is more to the story.

It appears there's a combination of user and cmputer based which I suspect is part of the problem.
