Hi,
I can't test this because shutdown is only a command on Windows XP it seems ...
that's what you're running right?
I did however try ipconfig and that works ..
<%
try {
Runtime runtime = Runtime.getRuntime();
Process proc = runtime.exec("cmd.exe /C ipconfig");
int exitVal = proc.waitFor();
BufferedInputStream bis = new
BufferedInputStream(proc.getInputStream());
byte[] streamBuffer = new byte[4096];
int byteRead = -1;
while ((byteRead = bis.read(streamBuffer)) > - 1) {
out.print(new String(streamBuffer, 0, byteRead));
}
} catch (Exception e) {
System.out.println(e.getMessage());
}
%>
I can have a look when I get home tonight on my XP machine if you have not
sorted it by then.
Cheers, Allistair.

};
I CAN successfully set the the system time and date using the same approach
though.
I have absolutely no idea on this now.
Thanks,
Andy
