I found post which enlisted all error code and description, here is the meaning of 2147549186 - Call was canceled by the message filter. reference - lists.berlios.de/pipermail/i18n-bel-svn/2010-November/… – Actiniform

Though still dont have the answer for my questions :( – Actiniform

I am not sure if this is the only source of that error code but it looks like it is RPC_E_CALL_CANCELED. This is a pretty generic error message that can occur under a wide variety of situations where your code is calling out to or consuming external resources. Almost impossible to help without knowing what the job you are running as a scheduled task is trying to do. – Freitag

implementation of the scheduled task is a .exe is run via batch file. The .exe fetches values from a asp api object call and refreshes a local DB. The scheduled task runs every 1 hour, six out of seven days it runs without problem. One more think is there any log that might be associated with windows task, if so how do i fetch it? – Actiniform

Answer 1

So I just had the same issue on my server after changing the password for the account that the tasks were run under. To solve I made a change to the task settings that required me to re-enter the account password.

this worked for me. I changed my Active Directory password the day before, and I was the user set as the task's Run As User – Radome

Answer 2

I had the same issue with the same error code. You can have a try on change following. === quote start === in task scheduler, click on the scheduled job properties >>> then settings

in the last listed option: "if the task is already running, the following rule appplies:" select "stop the existing instance" from the drop down list.
