IIS4 doesn't start - Event Error 14

Hi there We have a strange problem. On an WinNT Box (SP6a, all hotfixes) I get this error: The HTTP Filter DLL C:\WINNT\php4isapi.dll failed to load. The data is the error. (NT Event 14) 0000: 7e 00 00 00 I copied the dll into the %systemdir%, now the IIS starts at least. But every time with the error above. But, the php4isapi.dll is not needed by any of the webs running on the server. I configured it once running as ISAPI, but I removed this config. I installed PHP 4.06 (using the installer, overwriting the old installation). Do I need to reinstall the PHP Interpreter? How can I uninstall the whole php? there is no entry in 'installed software' ... simply delete c:\php, and kill the MIME mappings? Any help would be appreciated TIA an nervous junior - admin Tom ........................................
