Can't call defrag from perl script on Windows 2008

I would like to run a perl script that runs the defrag command on windows. When I try to just use

system('defrag C:');


I get ''defrag' is not recognized as an internal or external command,
operable program or batch file'. I get the same error even if I give the full path of C:WindowsSystem32defrag.exe. Also, any test for the existence of defrag.exe fails. For example:

if(-f 'C:\Windows\System32\defrag.exe'),

if(-x 'C:\Windows\System32\defrag.exe'), and

if(-e 'C:\Windows\System32\defrag.exe')


all fail. In fact they fail when testing for any .exe file. This works fine on Windows 2003, does anyone know why it no longer works on Windows 2008?

Thanks!

Chris
