In most cases, investigating a single log file by itself is not enough to find and fix a specific problem. Since many scheduling issues are security related, a good place to start is to examine security-related audit logs, such as the Windows Security Event log. In this case, the Windows Security Event shows us that the reason the task failed was related to a broader security issue, the log tells us that the event tried to perform an action which required SeTcbPrivilege level privileges.
The action performed by the task was assigned a lower privilege level, therefore, the host on which the task was scheduled to run, prevented it from running. In addition to showing that the task failed due to the tasks assigned privileges, it also shows information that indicates the root cause of the problem. Here, we can see that the security log indicates that the problem was caused by an executable process called taskhostw. In the final step, we will understand why this information is important and how we can use it.
By searching the Internet, we can see logs that identify a problem with taskhostw. Problems with this process are usually related to malware exploits or a defective Windows component, which controls folder access.

There are multiple issues with the MMC however as on almost every PC in my business the ask scheduler API will not open and has somehow been corrupted.
So you cannot edit, delete or otherwise modify tasks that were developed before the API decided not to run anymore. This seems to fix the API issue and it works again, however the tasks are often not visible anymore to that user since the tasks developed are specific to the user and not the machine in Windows 7. The other odd thing is that sometimes, although not with any frequency that can be analyzed, the tasks still run even though the API is corrupted and will not open.
The cause of this issue is apparently not known but there are many "fixes" described on various websites, but the user profile deletion and adding anew seems to work every time for at least a little while. We went with the system scheduler software from Splinterware though since we had the same corruption issue multiple times even with the fix that does not seem to be permanent.

Charles is dead-on with the logging, but Process Monitor from the Sysinternals suite might be useful for troubleshooting, as well. Sign up to join this community.
