First of all, I'd like to be able to monitor and preferably control the internet bandwith being distributed to the network to prevent a single user from ruining the bandwith for everyone. How would I be able to achieve that ? I'd like to achieve that in such a way that if the server is shut down I only lose monitoring & control over the network and wouldn't result in the rest of the network losing its internet connection. So any ideas ?
Another thing is all those PCs currently have a "public" account that has alot of stuff limited via group policies but offers somewhat similar services & applications. Would it be wise to make a single user account in the new server/client model for use on all these PCs or a seperate user account for each PC is best ?
