Question: I have scheduled a task to run a SSIS job using the Task Scheduler (TS). It is configured to run as a User who belongs to the Admin group. 

The security is 
"Run whether user is logged on or not" is checked
"Dont store password" is checked
"Run with highest preveilage" is unchecked

The scheduled task run ONLY when the user is logged in but when the user logs out the task doest seem to run. I figured "Run whether user is logged on or not" should run the task when the user isnt logged on. 

What am I missing?

Answer: 
Follow like this:

1. Type in secpol.msc /s
2. Select "Local Policies" in MSC snap in
3. Select "User Rights Assignment"
4. Right click on "Log on as batch job" and select Properties
5. Click "Add User or Group", and include the relevant user.
You might find in sig606's solution that the "Add User or Group" is greyed out in Administrative Tools->Local Security Policy->Local Policies->User Right Assignment->Log on as a batch job, Local Security Setting tab. If that's the case, you need to check your Group Policy in AD. A good reference is [here](http://www.networksteve.com/forum/topic.php/Problem_with_scheduled_task_%22this_task_requires_that_the_account/?TopicId=28407&Posts=6).

Basically on your DC, Administrative Tools->Group Policy Management->Computer Configuration->Policies->Windows Setting->Security Settings->Local Policies->User Rights Assignment->Log on as a batch job, edit and add your user there.
