From PHP3 to PHP4 under Win NT with Netscape Enterprise Server or iPlanet

Hello, I'm working for a long time with PHP3 with Netscape Enterprise Server and iPlanet under WinNT4 SP5. I'm unsuccessfully trying to install PHP4 as CGI with this web server. I get the following: When I ask for a test.php file placed on the webserver document root, a Dr Watson error occurs, here an abstract of Dr Watson.log file (ACCESS VIOLATION OF PHP.EXE) -------------------------------------------------------------------- -------------------------------------------------------------------- Une exception d'application s'est produite : App : (pid=258) <====== In my case PID 258 is PHP.exe Quand : 9/13/2000 @ 15:59:2.408 Numéro d'exception : c0000005 (violation d'accès) *----> Liste des tâches <----* 258 php.exe -------------------------------------------------------------------- -------------------------------------------------------------------- The error.log file of Netscape Enterprise Server reports [13/sept./2000:16:44:56] failure ( 246): for host 194.9.200.39 trying to GET /test.php, cgi-parse-output reports: the CGI program D:\php4\php.exe did not produce a valid header (program terminated without a valid CGI header (check for core dump or other abnormal termination) -------------------------------------------------------------------- -------------------------------------------------------------------- In fact when I launch test.php from a DOS Window to see the header the output is X-Powered-By: PHP/4.0.1pl2 Content-type:text/html This is a test (the echo function works) -------------------------------------------------------------------- -------------------------------------------------------------------- With PHP3, the header was "Content-type:text/html" but no other ligne before and everything worked well. Do somebody know if this new header (X-Powered-By: PHP/4.0.1pl2) can produce a Dr Watson error? or Has somebody successfully installed PHP4 under Netscape Enterprise Server or iPlanet ? Thanks a lot
