Fix for Microsoft Windows Media Player asking for authentication


When accessing external links using Windows Media Player on Windows 7, the Media Player asks for user authentication on NTLM-enabled proxies, such as Guardian.


This prompt appears because Windows Media Player struggles to determine if the proxy is a local address or not.

Microsoft has issued a fix to address this. To download the fix, and a detailed description of how to install it, go to http://support.microsoft.com/kb/816089.
