Upon restart of the server, any nondefault Terminal Server printers are deleted. Specifically, a check is made against the port name of the printers that are configured on the server. Any ports that are found to be in use that begin with TS# are deleted upon server restart. This clean-up activity is only triggered upon server restart. Restarting spoolsv.exe will not trigger this activity.
