Solved What does task scheduler last run result 0xFFFFFFD5 mean

June 9, 2017 at 21:36:49
Specs: Windows 7 pro, 16GB
I have a task that worked once and now gets a Last Run Result of 0xFFFFFFD5. I've searched and cannot find what this return code means. Microsoft's website details a bunch of return codes but nothing resembling this one. Typically that full word hex number would be a negative number (high order bit is on so it could be hex -2B = -43) or a very large positive number or a possibly a composite return code. In any event I can't find anything on this.
Anyone know of it or where this might be documented?

You haven't talked about this task at all so I'm assuming your task is some script? And your script doesn't do any error checking or setting? If so, the error would bubble up from the program's crash. But the error itself has nothing to do with Windows.

C:\>err 0xFFFFFFD5
# as an HRESULT: Severity: FAILURE (1), Facility: 0x1fff, Code 0xffd5
# NOT FOUND: 0xFFFFFFD5

Whatever you're trying to run is throwing that value, so check its documentation.

Error code 43 signifies a non-working device, often a USB device.

The answer is that I inadvertently deleted certain called programs/subroutines in the execution directory and this return code was returned by the system when a called subroutine was not accessible.
So neither answer is correct although a non-working device is the closest. I knew it was not a return code of mine because I set all return codes to positive values and nothing remotely resembling a FFFFFFD5 is returned.

Where did you find that HRESULT... Apparently a compound error code from a windows header file.

It makes sense. ffd5 = not found and as I mentioned it was a called program that was not found due to my inadvertently deleting it from the execution directory. Once I determined that and restored it the error went away.

BTW, all of my programs do extensive error checking as one might expect of someone who has worked (recently retired) as a software engineer for 35 years. I'm just not as conversant in C++ as I am in IBM assembler and COBOL (I came up a mainframe guy and C++ is not my 'first' language). This program was written in OOREXX - which I find is great for quickly writing many little utilities as this backup type program is.

Thanks.

The tool's called Microsoft Exchange Server Error Code Look-up, but it contains info on just about every Microsoft appointed error code you'll find in Windows. https://www.microsoft.com/en-us/dow...

If you're looking to avoid downloading anything, you can also ask PowerShell, but it's a little more cumbersome.

PS C:\> New-Object ComponentModel.Win32Exception 0xFFFFFFD5
Unknown error (0xffffffd5)
