Users can successfully get a DHCP address and all looks normal there, and the certified list for the successfully logged-in users looks to be fine. But for the ones who cannot get the pop-up for logging in, that's where they are stopped: the Agent will not pop-up to allow login. Nothing seems to make it want to pop-up, and then you see the "OS mismatch detected" in system tray. The next day, all will work correctly. It appears to be happening over 6 CAS boxes in our wireless network, but not to everyone...sometimes it will work, other times it will not. Theoretically, I can see that perhaps the 8905 udp communication could get blocked or interrupted in some way, thus not allowing the pop-up to happen, but why then the message "OS Mismatch Detected"? You'd think the machine would just sit there, with no Agent pop-up, and no error message.
