I am trying to run a script from a win32 machine (win2k) with php4 and an apache server (1.3.20). I get the warning of Unable to fork... followed by a number of Undefined variable: warnings. The script runs fine on my ISP Host (linex machine). So I am wondering if 1) it is a config problem on my end, either php or apache or 2) if it isn't possible to run this script on a win32 machine. Thanks for the help
