Hi! I solved the problem. Php 5.2.1 still use cmd.exe for run any executables (or may be I have made mistake in "other_options"). But Win2003 does not give read and execute permission on cmd.exe for simple users and guest users especially, and IIS 6 (unlike Apache) runs website under very restricted user, who, of course, have no permissions for reading and executing the cmd.exe. If you need to run executables in php code under IIS6 control, you must give read and execute permission on cmd.exe to users, IIS6 uses to run websites under.

I don't know, but this may give you a clue? Grabbe from http://se2.php.net/manual/sv/function.proc-open.php "Not: Windows compatibility: Descriptors beyond 2 (stderr) are made available to the child process as inheritable handles, but since the Windows architecture does not associate file descriptor numbers with low-level handles, the child process does not (yet) have a means of accessing those handles. Stdin, stdout and stderr work as expected. Not: If you only need a uni-directional (one-way) process pipe, use popen() instead, as it is much easier to use."

Could anyone help me. Here is my problem. I need to start new external process. I do it by the next code: $descriptorspec = array( 0 => array("pipe", "r"), // stdin is a pipe that the child will read from 1 => array("pipe", "w"), // stdout is a pipe that the child will write to 2 => array("pipe", "w"), // stderr is a file to write to ); $hf = proc_open( $ex_path, $descriptorspec, $pipes ); $ex_path is a correct path to my executable. However, I get "CreateProcess failed" when it runs. I have IIS 6, running in its native process model. Also I have PHP 5.2.1. What's wrong?
