I suspect either your network engineer coworker misspoke what he meant or you misunderstood but - it is not unheard of for something on the network to start behaving badly and do what he described. In fact, I've actually seen just that happen more than a few times. Some user has plugged in a rogue access point because they want wireless where they are in the building and for some reason it isn't there.

Blah, blah, blah

What do you know, you're just an expert!!

Mike is absolutely correct. If the situation is a rogue AP, that's very bad juju. If you are talking about a device that was bought, configured and installed for the purpose, and it's not a $50 home-style unit, I would hope it shouldn't be a problem.
