If an error occurs, the Task Scheduler APIs can return one of the following error codes as an HRESULT value.

The constants that begin with SCHED_S_ are success constants, and the constants that begin with SCHED_E_ are error constants.

Note  Some Task Scheduler APIs can return system and network error codes (64 for example). You can check the definition of these types of error codes by using the net helpmsg command in the command prompt window. For example, the command net helpmsg 64 returns the message: The specified network name is no longer available.
