Help deciphering a WMI return value

I have a script to do mass shutdowns of machines for when we have
planned outages, etc.
I use a wmi call to do an immediate shutdown as one of the options and
check the return value. Usually it's the easy to understand 1 or 0,
but for a few machines it comes back as 1271, which I can't figure
out. Here's the wmi call:

(gwmi win32_operatingSystem -ComputerName
$svr).Win32Shutdown(1).ReturnValue

It's not a permissions issue (as far as I can tell), and it seems to
be independent of server OS type, in that I have seen it on XP and
2003 x64.

I looked around in the ms docs on wmi return and error codes and found
nothing useful. Any ideas?

Never mind, found it in the general Windows system errors:
ERROR_MACHINE_LOCKED 1271
