Windows workstations in the UBC ECE rejecting logons (Sep 10, 2012)

A number of Windows workstations in the UBC_ECE domain (such as the workstations in undergraduate computer labs) are rejecting logons with the message, "There are currently no logon servers available to service the logon request." Today only, you may need to reboot the workstation to clear this error.

The problem is that some of the workstations have acquired a faulty DHCP lease. The problem will resolve itself once these leases expire. In the meantime, the simplest solution is to reboot them to force them to acquire a new DHCP lease.
