Unable to fork errors

Hi, I'm sure this one has been asked a thousand times, but I can't find it in the list archives or the web, just lots of people with the same problem. I'm trying to execute a program from within a php script, I've tried system, exec, etc., but all are unable to fork. I belive this was a bug, but was fixed (now running latest 4.1). I think the problem will go away if I allow IUSER_MACHINENAME access to cmd.exe on my win2k box, but I don't want to do that for security reasons. Does anyone have a secure solution to running an executable from a php script running on a win2k server?
