At one of my client's sites I need to keep my users unauthorized devices off the wireless. They all know the SSID and Password because many of them have laptops that need the wireless. I'm running out of IP address's and we have sent out numerous emails asking them to stay off, but like most users they ignore IT's email. I'm currently running Server 2003 as the GC/DC (but have 2008 servers in place) and 2 Netgear WNAP320. I've seen several posts similar to what I'm looking for but they seem to deal with Linux. My question is how do I go about doing this without migrating (scheduled for the end of the year) to a new server and is it possible to do this within Server 2003?

Thanks msindle
