I performed a Windows 7 SP1 install yesterday as it was pushed to me as a Windows update. Since installing it the default page on a website I develop (index.php) no longer loads if I just point my browser to the site on my local machine. I've checked and Default page is enabled and index.php is at the top of the list and if I browse direction to index.php it all works just fine. I am authenticating as myself rather than the default user. This has been working just fine for over a year and only stopped working after the SP1 install. No other significant changes have been made to this machine.
I'd really like to get this working again. Whilst it's not the end of the work it is a real pain.
