Sorry-just saw this. What exactly are you doing to allow Net Send? I would guess that allowing net send should have nothing to do with live messenger working or not (unless Live Messenger relies on the Alerter service but if its enabled , that should not impact IM). As for disabling Wireless, you can't really do that as a function of whether it's on your network or not. If you are worried about users connecting to non-corporate WAPs while they are in the office, then GP against XP clients won't help you much. The Wireless Policy that is supported on XP is pretty limited. Vista is better at this. You might be able to do some kind of IPSec tunnel while on the corporate network that prevents non corporate networks from accessing your internal network, but it would take some work.

I am trying to enable NET SEND and at the same time deny users the ability to use live messenger, those options didn't work. Further more I am trying to force disabling of Wireless on laptops connected to my network, I didn't find any effective way of doing that through GPO. Any thoughts?
