New Post: Unauthorized Exception when creating/deleting tasks

Great news! I found the solution based on the following thread: 

http://social.technet.microsoft.com/Forums/is/winserverGP/thread/6eb2bbb4-4444-47f4-b4f1-dbac43f33561

Based on the two recommendations, 

1. Add a Execution Time limit
2. Created the task on a sub folder rather than the root folder

I'm not sure how critical #1 is, however #2 will get you past this exception. Creates and Deletes all work now :)
