Hi, I have five tasks in task scheduler that runs once everyday at a scheduled time. I noticed that each task triggered two instances at same time and one instance finished a few seconds after the other one. The same happened with all 5 tasks. Any help on fixing this issue please?

Hello, I would suggest you read the below post: Strange Problem in Windows 2008 Task Scheduler http://social.technet.microsoft.com/Forums/en-US/winservergen/thread/29a37921-3e27-4c88-b387-3dd394302298 I was getting the same errors every time my process would start up. The process would run without problems, but would appear to attempt to start up multiple times. The trigger for the task was as follows: Settings: Daily, repeat every 1 day Advanced Settings: Repeat task every 15 minutes for a duration of 1 day To fix this, I changed that to Settings: One time Advanced Settings: Repeat task every 15 minutes indefinitely I'm not sure why this fixed the problem, but it did. I hope this works for someone else as well :) Checking "Synchronize across time zones" under triggers solved my problem. Not sure if it remains consistent and doesn't fail again ;)
