Installation help - what did I miss?

What am I missing? I'm trying to install PHP 4.0.1pl2 on my NT 4.0 machine (service pack 3), running Microsoft PWS 4.0 (as a developement platform). I've read the following documentation: 1. the readme file that came with the installation package 2. http://www.php.net/manual/html/install-windows95-nt.html 3. http://www.umesd.k12.or.us/php/win32install.html ... and I've done the following (according to README.TXT): 1. unzipped the php files into d:\program files\php3 2. copied PHP4TS.DLL to c:\winnt\system32 (MSVCRT.DLL was already there) 3. copied php.ini-optimized to c:\winnt\php.ini and: made doc_root = "d:\project_files\www" (top of the PWS web directory) made extension_dir = d:\program files\php3 turned on the following extensions: extension=php_dbase.dll extension=php_dbm.dll extension=php_mssql.dll extension=php_odbc.dll 4. edited PWS-php4.reg to look like... REGEDIT4 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\w3svc\parameters\Script Map] ".php"="d:\\Program Files\\php3\\php4isapi.dll" 5. added Execute access to the top directory of PWS, using PWS Manager. ... and following http://www.umesd.k12.or.us/php/win32install.html, I did the following: 6. edited my registry following the instructions under "Windows 95/98/NT and PWS / IIS 3"; I'm only adding .php as an extension for now. (I was somewhat surprised that the registry information wasn't included in README.TXT. Is this a left-over from PHP3 ?) I rebooted. Then I got a simple working .php file from my ISP (who supports PHP3) and put it in d:\project_files\www. I pointed a browser at this file (http://127.0.0.1/test.php) and stepped back to watch. A connection was made to the web server, then it just sat t here, not serving up anything ("Waiting for reply.."). I checked NT Task Manager and saw that php.exe was running. Other pages (asp and html) were still served up nicely. I've dug around a bit to see if there was more information about PHP installation, but I didn't come across anything that helped. So, what did I miss? Thanks for any help. - larry
