I have a series of scheduled tasks that have been running fine until about 2 months ago. Now they seem to run sometimes, at the scheduled time, but not consistently. The tasks will run if I reboot the server but not if the server has been left on for some time. I suspect a Windows update has caused the problem but having investiigated all the updates installed I cannot see which might have caused the problem. I've checked all permissions etc and am happy that everything is set OK - and the fact that the tasks will all run after a reboot confirms that the settings are fine. Anybody else have this problem?
