Installing PHP 4.2.3 n win 2k

[rsuguna1]

hi,

I moved the php.ini to winnt folder then Under ISAPI Filters,
added a new ISAPI filter. Used PHP as the filter name, and
supplied a path to the php4isapi.dll. then Under 'Home Directory', clicked on the 'Configuration' button.
Added a new entry to the Application Mappings. Used the path
to the php4isapi.dll as the Executable, supplied .php as the
extension. then change the followin in the php.ini file

doc_root = C:\Inetpub\wwwroot

extension_dir = C:\WINNT\Temp\php\php-4.2.3-Win32\

but when tried to access a php script file via the
browser, I get a server 500 error.

Please HELP ME!!!!!

Don't install PHP as a module on IIS. It's just not stable enough. (see here for more details, just above the diagram in grey).

Install it as a CGI instead (also much easier as well)
