Hello,
Last week, a customer called to report that her workstation was not booting. Long story short: There was a problem with the hard drive. I cloned the drive to a new disk and that brought the system back up.
While looking for damage after the clone, I noticed that the Task Scheduler UI does not launch. Specifically, if you open "Task Scheduler" from the Start menu, nothing appears. If you access the Task Schedule from Computer Management, Computer
Management closes unexpected. (The same thing happens when you add-in the Task Scheduler to a new MMC.)
To be sure, this problem could pre-date the hard drive problem. I really don't know.
I have no reason to believe that task scheduling isn't working. The service runs and I've scheduled a task from the command line successfully. But, admittedly, the loss of user-friendliness is kind of a big deal to the end user.
The only evidence I've been able to track down so far is that with each crash, the Application Log shows
EventID 1023:
.NET Runtime version 2.0.50727.5477 - Fatal Execution Engine Error (000007FEF80C54F6) (80131506)
What I've tried:
1. I've run the dotnet repair tool from Microsoft which found problems with 4.5 and repaired them.
2. I ran SFC which reported it found problems and fixed them.
3. I've tried known-good copies of Tasksched.msc.
4. I've cleared out both the Tasks folder and the cache in the registry to see if a particular entry was causing the crash. No difference.
What am I missing?
Cheers,
