Vista - Running external app from an HTA on Windows Server 2003 x64

Hello,

I'm having a problem with an HTA running on Windows Server 2003 x64.

The HTA executes a VBScript statement to initiate a shutdown:

result = WshShell.run("shutdown.exe /r /c ""Maintenance Mode Reboot"" /f /t
30 /d p:0:0",7,true)

This statement works fine on a 32 Bit version of Windows Server 2003, but
not on an x64 version.

Apparently, since no path has been given, the system searches for
"shutdown.exe" in %SystemRoot%\SysWow64 and not in %SystemRoot%\System32,
where shutdown.exe is located.

I tried everything to get the correct path into the script, but nothing works.
Neither putting in the complete path directly, not working via the
environment variable.

The error message I get is "The system cannot find the file specified".

When issuing the shutdown command with "cmd.exe /k " in front of it, I
cannot manually issue the shutdown command from this command prompt window.
It just doesn't find the shutdown.exe, even with a fully specified path.

Can someone please shed some light on this? I feel a bit lost here.

Thanks a lot!

Regards,
André
