We installed a NAC appliance last summer.   This box guarantees that no
one plugs into the network with anything that is not:

	a.) included in a mac address list of exceptions (solves the
printer 		problem) or

	b.) authenticated as all others must pass thru several checks
(AV, 		Updates, etc) and then have an AD logon to access the
This has worked really well for us and I feel reasonably certain that I
know of every device attached to the network.

How do you enforce that for printers that people/depts buy for
or do you have total control over the network, so they can't connect
without your OK?
