I'm sorry, but it is at fault.   I'm sorry I did not see your earlier
postings - I would have told you how I had already made that mistake..

yes.  one by one, you will take down their whole network.

the easiest way ?  unplug yourself.  plug your clients directly into
your Terminal Server, then connect your Terminal Server to their network
via its' eth1.

yes, you will have this to contend with for some time.  It is very sad
really, how they will be coming to you for *your* advice in a couple of
years...  8-/  how embarrassing for them.

Sorry to advise so readily, but you must lose this focus quickly, and
make very sure they never, never, have an issue with your network again,
or things may escalate further.  Even Asst Principals have been known to
suddenly "lose support" in the face of unprecedented criticism.

"squeaky clean" is the ticket..

take care out there..
