Domain controllers are all native @ 2008R2. The situation is there are kiosk running XP and W7 now. They all log on using the same security profile but different roaming account user ID's. We confine web browsing to the internal network, not allowing them outside access through a proxy. Seems over the past 2 months the Win 7 kiosks will not authenticate through the proxy but all the other security lockdowns are in place and working fine. Not being the admin of the proxy I don't know where things have gone wrong, but I have been told that the proxy relies on the DC for authentication. XP kiosks are working fine with the proxy validation. Any suggestions on where to look ? Thanks -BDP
