Cannot Open an Anonymous Level Security Token in IE

Recently I had an issue in Internet Explorer 8 on Windows 7 Enterprise 64 Bit, when logging into a web page. Every time I logged in with the correct credentials it would flash and NOT open the secure page. The credentials were correct and the same page opened correctly on another computer.

Upon investigation I found the following error. This was found in the bottom left hand corner of the status bar in Internet Explorer.

"Cannot open an Anonymous Level Security Token"

Enable Password URLs in Internet Explorer 8 (Windows 7, 64 Bit)

Have you ever received a link like the one below for a website where the user name and password is incorporated in to the URL?

Example: http://username:password@websiteaddress.com/

When clicked these URLs take you to a website and automatically log you in to it.

In older versions of Internet Explorer it used to just work, however in the IE7 and above Microsoft have disabled the feature for security reasons.

However this can be re-enabled if required by a simple registry fix.
