| If you wish to block MSN messenger from successfully connecting to the
| messenger service do the following on your network firewall:
|
| 1) Block outbound access to TCP port 1863
| 2) Block HTTP access to messenger.hotmail.com
|
| This will stop the initial access to the service and therefore block the
| application and all it's other communications.
