I'm just a lowly developer, but a scheduled (2:00 am) VB.Net console app job I inherited is intermittently not running to completion. About half the time, it just doesn't run to completion, logging and event: Task Scheduler successfully completed task "[appname]" , instance "{3f00cbd6-b40e-4e74-a0da-4def71b4d7db}" , action "D:\Scheduled Tasks[foldername][appname.exe]" with return code 3762504530.

I found one other mention of that return code on the web, and the guy included the description of some settings; below are our analagous settings with answers provided by our Networking guy.

I'd be pathetically grateful for any advice or direction... thanks in advance.

Does the job "run whether user is logged in or not"? - YES

Is the job "run with highest privileges" - YES

What's the server OS? - Window 2008 R2 Standard

Is it true that "the only conditions set is to wake computer to run"? It is not set to wake the computer to run the task. However, it is not going to sleep and the task is running. It's just exiting abnormally.

Are the "settings are allow task to be run on demand / stop task if running more than 3 days / if task does not end when requested force it to stop"? YES, it can be run on demand; YES, it will stop the task if it runs longer than 4 hours; YES, it will force it to stop if it doesn't end as requested.

I believe that return code is a generic .NET console app crashed code. The way the job is set up in Task Scheduler is not causing this issue.

Check the Application event log on the server for any errors that occurred near the time the job 'completed'. Those events should give you more information as to why the job exited abnormally, so you have some idea where to start troubleshooting.

If you check the Event Log-->Application, you might get detailed info there. You should be able to find an error record with exception code 0xe0434352 which is the Hex value of 3762504530

I had this same issue with a Task Scheduler job 'successfully completed' with a return code of '3762504530' showing in the Task Scheduler History. The Eventlog for my scheduled task provided the following information

Description: The process was terminated due to an unhandled exception.
Exception Info: System.IO.FileNotFoundException

I tried a few other things, but finally I ran the program from a command line and discovered that some of the 3rd Party DLL's weren't installed on the server.

What is the same about your issue and this one? – Ryan Babchishin Oct 19 '15 at 20:56
