Disable wireless network devices while wired device is active?

We have a number of laptops using windows xp sp2. These laptops have built
in wireless cards and many of them also have cellular wireless cards.

For security purposes, I am looking for a way to automatically have any
wireless device deactivate while the client is on our network using a
hardwired connection.

Is there a setting inside xp that I can use to achieve this goal or is there
possibly a group policy setting that I could enact to accomplish this?

Thanks in advance for any response.
