This happened to me too. Then I copied the php4ts.dll file into the %SYSTEMROOT%\SYSTEM32 directory, and everything worked great.

Hello,
I have installed Windows NT Option Pack 4 and it includes IIS 4. I've tried to install PHP. The CGI-version went fine, but I want to install the isapi-version.
I followed the instructions in the install file and I have edited the php.ini file but when I try to open a PHP-document, I get either "The specified module could not be found" or "Server internal error 500". Any ideas?
