Or something > else caused the problem, not the permissions? Please help me.:) On windows, php uses cmd.exe to do exec() stuff. IIRC< if your web server/php script is running as an underprivileged user (which it should be), it probably don't have read/exec access to cmd.exe. This is one possible cause of the fork error you mentioned. You can solve this by giving your php script access to cmd.exe, or copying cmd.exe into the directory that contains your php dll or exe. (you may have already done this, or this may be different in newer versions of windows -- I haven't had this issue in a while) Tyler -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
