heads up: shutdown.exe on windows 64
Pedro CR
Just wanted to share something that may be of interest.
One of the installations I run is an SBS 2003 R2 with a second server that
runs windows server 2003 R2 x64
I was setting up an automated shutdown script on the UPS setup to stop some
services and then call shutdown.exe to shutdown the computer.
An equivalent script runs fine on SBS 2003 but on windows x64 all goes well
except the computer WON'T shutdown.
After hours with process Explorer the reason is this: The UPS software
starts the shutdown script under a 32 bit process and thus shutdown.exe is
initiated by 32 bit process.
In this situation, all calls to executables that exist in %windir%system32
are silently redirected to %windir%\syswow64 where supposedly exist the 32
bit versions of what exists in the x64 version of system32.
However there are some tools that have no 32 bit equivalents and thus don't
exist in syswow64 (shutdown.exe is one of them). So a call to shutdown.exe
ends up failing since there is no %windir%\syswow64\shutdown.exe
Bottom line, when using windows server x64 it is impossible to run
shutdown.exe from a script initiated from a 32 bit process without some
tweaking.
There is some info on that here

Just wanted to share this in acse anyone runs into the same situation.
Thanks.

directions. There are, usually, workarounds. Or use 64-bit software, of
course. Sadly the UPS manufacturers have been a bit slow to provide native
versions, though I'm sure that will change as we move forward.

however my point here is that one would expect the 32 bit experience to be
fairlly transparent. As it turns out there is a sysWOW64 fot taht purpose
but it does not include all the equivalent tools that exist on the 32 bit
versions of windows (or in even in system32 of the 64 bit versions).
This makes little sense..... shutdown.exe is one of those that don't have a
32 bit equivalent residing in sysWOW64...
However oddly enough, I copied shutdown.exe to a different folder (one not
affected by folder redirect) and it works perfectly when called from a 32
bit app.

line app, there's no reason why not - it's just that the "real" system32 is
hidden from a 32-bit app. (you could even get away with simply copying it to
the SYSWOW64 folder, I'm sure. Or get really smart and do a hard link, with
mklink.)

I have the same problem.
I use the shutdown.exe in my reboot.cmd with %windir%\system32\shutdown.exe.
I don't find the shutdown.exe(no file exist) on some servers with 64bit .
On 32bit systems is the commandline okay.
Can you help me, please.
Best regards
Norbert

This is a known issue with 32-bit/64-bit interaction. You see it in both
directions. There are, usually, workarounds. Or use 64-bit software, of
course. Sadly the UPS manufacturers have been a bit slow to provide native
versions, though I'm sure that will change as we move forward.
