We have begun to roll out dot1x configuration on our fleet of switches to support a basic authentication and posture check for our NAC Framework deployment. Previous to this, we spent a couple of months deploying the Trust Agent. In the time between deploying the client, and turning dot1x on the switch ports, some users have un-checked the "Enable Client" option available to them in the system tray icon, and the Wired Client. Obviously when dot1x is applied to the port, the supplicant forwards the authentication request to the client, and waits forever for a response, leaving users trying to login waiting for 20 - 30 mins for the login process to complete. My question is thus, is there any way (registry setting, config file setting) to force the client to always be enabled?
