Task Scheduler Stopped Working

Hi
I have a Small Business Server 2011 Standard which has been running fine for the past year. I have Symantec Backup Exec running with RD1000 cartridges to backup all the data.  However, I also have an attached external hard drive which I use to backup folders by running a batch file which copies from the server to the external drive.

This batch file is run using the Task Scheduler. It has been running fine but a couple of weeks ago it stopped. Task Scheduler will open but when I click on "Display all running tasks" I get the message "Task Scheduler is not available. Task Scheduler will attempt to reconnect to it".

The service is running but greyed out so I cannot restart it or stop it.

Any ideas?

Thanks

is it possible that the Task Scheduler was turned off in your domain group policy?

you can try run the scheduler.reg used to fix this problem on vista machnies (backup registry key before hand):
task-scheduler-service-properties-are-grayed-out

another option is to delete values under KEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tasks
and delete everything in the C:\Windows\System32\Tasks.
and then restart server.

via Group Policy Management Editor:
MyDomain Policy --> User Configuration --> Preferences --> Control Panel Settings --> Scheduled Tasks

the Small Business 2011 Server. There is only one server. I am looking at the Group Policy and I cannot find any items for the task scheduler which are enabled.

I have merged the scheduler.reg file. Do I need to do the other 2 things you mention as well. Also after the merge do I need to restart the server to force the changes to the registry?
