Backup Fails Due To Task Manager Being Disabled

I attempted to backup my systems the other day when I recieved an error code. After searching this forum, It was determined that the code made reference to the fact that a necessary service was not running, in this case the Task Scheduler.I have used the Services program (as an administrator) to attempt to restart this service, but in the properties every option in grayed out. I have checked and all dependant services for the Task Scheduler are running normally. I have run the checkdisk utility from the command prompt, and it did fix some corrupted files, but even after that the options are still greyed out.
