Policy not executed on client machine as scheduled

Hi,

I have a powershell script that runs on a particulare computer to backup a file.

Problem:

I set up the task as a policy to run everyday at 2am. The status of the policy on the target computer shows "Compliant" with the correct Next Run date/time.

But the policy does not run at all! The policy never ran once actually!!. The task executes sucessfully when ran manually. It seems that there is a problem with the Symantec agent. I tried resetting the agent but the problem persisted. For you infor, the policy is activated.

Are there other troubleshooting steps that I should take/look out for?

thank you in advance
