Dell Wyse think client failing to authenticate with domain after reboot

All the dell wyse thin clients on our production floor fail to authenticate with domain after reboot. When I try to log in after a reboot I get this error message "The trust relationship between this workstation and the primary domain failed." The only way around this is to pull out the Ethernet connection, then log in and then reconnect the cable. The Wyse units are never rebooted and often go 6 months + without a reboot as they are constantly running for production. Has anyone had this issue before and if so any idea how to fix it?

Thanks
