Troubleshooting: When the "Mandatory Profile" Can't Be Found

If one of the public workstations is turned on, but won't let you log it in because it can't find its mandatory profile, it might have been disconnected from the network. This will happen if the black network cord has come loose, either from the back of the computer or from the data outlet in the floor. (Those restless feet again!) Check the floor outlet to see if the black cord with the small head is securely inserted, and check the back of the CPU, where the cord goes into an opening marked with the network symbol (three squares connected with straight lines, resembling computers connected by wires).
