We rely on scheduled tasks, and schedule them using the GUI, using a service account. The server is Windows Server 2003 R2, Standard Edition, SP 2.
Every once in a while, the scheduled tasks don't fire. Often the "Last Run Time" shows that it thinks it ran, but nothing happens. I don't think it is the task itself as they will all fail.
The only thing we've been able to find to fix is to reboot the server.
Any hints as to what I should look at?
