Ye we had the same problem that for the internet block to work you have to manually put in the 8080 port as we use an isa proxy.
Although just a few suggestions make sure your control and the clients are all up to date, its not in front of me but its something like tools --> check for updates, (you need to update the controller first) then once thats updates, you can select all the clients and click tools --> client maintenance --> update clients.
And well we mainly use Abtutor for remote support to machines, and also to keep an eye on what the students are doing, although we also use the logging as its just faster if you just want to see the last persons on there history although we also use the ISA for history checking. But also the policies are very useful for when you have kids trying to play flash games off there documents, or excel golf games, things like that.
