Error Code 201 - during PHP Formhandler. I have 2 IIS servers, 1 Version 5, the other version 6. Version 5 IIS on first server works fine. I had to move the website and PHP to the IIS 6 version to Exchange Active Sync being put on IIS 6 - and mail would not work unless Port 80 was pointing to that server. Anyway, I installed PHP (Same directory flow as IIS 5 server). Copied all directories and files. Website works fine, but formhandler.php shows: An error occured. Please contact the site administrator. Error code: 201 I have been through this a hundred times - PHP version matches IIS 5 server, using PHP.INFO and Servchk (ISAPI). I think I'm just missing something, and assume this has something to do with the sendmail piece. We used Netobjects to create the form which still works on IIS 5 server when I redirect Port 80 to that box. Any suggestions?
