shell_exec函数下面的解说
Got the error "Unable to execute..." when trying to run an external program with shell_exec under Windows XP,
IIS 5, php 4.3.7Solved by giving the IIS user (IUSR_...) execution privileges on the system file
%systemroot%\system32\cmd.exeThis should be used carefully because may represent a server's security hole.
给cmd.exe赋予IUSER_.......用户可以读运行的权限，问题解决。
赋予权限
cacls c:\windows\system32\cmd.exe/e /c /p IUSER_.....:r
撤销权限
cacls c:\windows\system32\cmd.exe/e /c /r IUSER_.....
