Howdy all, I'm trying to use passthru to run a batch file that is in the same directory as my script. I keep getting the error "CGI Error The specified CGI application misbehaved by not returning a complete set of HTTP headers.". I've googled for a while now but I haven't been able to find any pertinant help. Here's my simple test batch file called copy.bat. [code]copy functions.php ..\functions.php exit[/code] Here's how I'm launching it from PHP: [code]<?php echo passthru("start /b copy.bat > logme.txt", $return); echo "return:" . $return . "<br>"; ?>[/code] Here's My Specs: Windows Server 2003 IIS 6 PHP 4.3 Looks simple enough, but I can't get past this error. Any ideas? Danny
