[squid-users] Squid not allowing WLM (windows live messenger) to go through. any tip ?

�We are using a config script for our proxy, with the proxy being a Squid Proxy Server configured to allow traffic through, and in specific, ports 1863 and 443.. I have tried the following to fix this issue as many forums have suggested:

��� Checking and unchecking the "Automatically detect settings" option in the LAN Settings of the machine's local Internet Properties.
��� Leaving both the "Automatically detect settings" and "Use automatic configuration script" options checked.
��� Uninstalling Windows Live Messenger and the Live Essentials suite and re-installing those.
��� Flushing the local DNS cache.
��� Clearing all internet caching and history.

Even after trying all the above the problem persists. The users are still able to use the Messenger service through their Hotmail accounts over the web and when accessing Live Messenger at home on the same machine. Not sure what to try or where to approach this from anymore and was wondering if anyone managed to solve this issue already and could provide some tips. Any help would be much appreciated.

Thanks in antecipation!
