My PHP5 phpinfo() test page runs fine, except ... 1. Page authentication is required the first time a browser instance accesses the page. 2. Using an ISAPI filter, pointing to php5isapi.dll, (and re-starting IIS, of course) results in the browser returning the following error: -2147467259 (0x80004005) Why? Is this expected behavior? fyi: I'm running a fresh XP Pro installation with latest service packs, IIS 5.1.2600 and Mozilla/Firefox 0.9.2 browser. IIS is running default settings: Anonymous (checked) UserName: IUSR_machine Allow IIS to control password (checked) Integrated Windows authentication (checked) -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
