Hi everyone, I work at a school and have Microsoft Server 2003, Watchguard Firebox firewall, Cisco 2821 router, Cisco 3560 switches and Cisco 1240AG WAPS. We have Dell D630's with Intel ProSet Wireless. I decided to use Microsofts Zero instead of the ProSet software for ease of use. Anyways there is a bar down the street that has open wifi and the students get on it to bypass my filter. After the first student does that then the wireless defaults to that wifi network instead of ours and the rest of the students that use that computer cannot log in to our domain. I've heard Cisco has something to knock down other wifi signals etc but it's expensive and was hoping maybe there was a setting or policy I can enforce on the computers locally or through AD to solve my dilema. I thought I was out of school but teachers and principals are still driving me crazy!
