When it comes down to it, it's our (the IT folks) network. If there's an AUP stating you can't use a personal machine on the network, you're not using a personal machine on the network. If it states you can use a personal machine, but have to have one of our admin accounts installed on it and you don't want one of our accounts on it, it doesn't connect to the network. If we find that you have connected a personal machine to our network, it either gets confiscated, and you get to explain yourself to the director of technology, and/or, you find yourself a new job.
