Prevent users from adding "Preferred Networks"

[iLinkTech]

I'm looking for information on how to prevent users from adding entires into the "Preferred Network" area on their computer's wireless client configuration (XP SP2).

Basically, our company policy is that any computer that connects to the company wireless cannot connect to any other wireless network. I have a wireless access policy via Windows 2003 Group Policy enabled which does a good job of blocking most changes but users can still add other APs as preferred networks.

Any ideas? Registry settings, etc?


Thanks...
