I created a scheduled Defrag on one workstation via Desktop Central. I set it to perform when the computer is idle. This appears to be causing the current user to be logged off when it starts. This has been going on all morning -- that's the only thing that has been changed since last week, so I feel this task is the culprit. I deleted the task so it no longer shows up. Is there a way I can *manually* disable so that it does not defrag due to this task that I previously created??
