Does anyone know how it's possible to log into a windows domain (no local account) from a Windows XP computer using WPA when the user has never logged in before (making cached credentials impossible)? I work at a high school. We have several mobile carts with laptop computers that do NOT have local accounts for each student. Therefore, each student is required to logon to the windows domain using wireless. This works fine using WEP. However, using WPA, with the automatically supply windows username/password/domain checkbox selected, a user that has never logged into that machine before is not able to log on. The Windows computer complains that the domain controller is not available. This, of course, is true because there are no 'up' network interfaces. But wouldn't it be logical for Windows to first supply the entered credentials to the access point for authorization to the WPA WLAN and then supply those same credentials to the domain controller? Is that the way it works, is there some other way, or are people that have never logged on to these laptops before condemned to never logon at all given our new WPA infrastructure? Stefan
