Ideally I would like to be able to centrally manage wireless clients with Group Policy. Using win2k3 server, winxp clients. Using PEAP authentication will allow GP to be used. Would like to use the Microsoft wireless client for our wireless connection. However, prelogon, or single-signon is not an option with XP and the MS wireless client. It is a new feature in Vista, but we cannot upgrade to Vista until all 400 apps have been tested. Without the prelogon, drives won’t map and logon scripts won’t run because the mobile devices aren’t authenticating to the domain. Other than using another wireless client, is there a script or other method to use to get a prelogon? or addin for the ms wireless client?
