I have decided to do a few tests on the XP firewall, now I have in the settng area msmsgs then a UDP, ICMP OR TCP port number now by disabing these and stopping them from accessing the internet it turns my PC into stealth, however what do they close?

It says, stealthed or no computer at this IP, also everything, even my network is working!

It's a way to harden XP firewall then, disable every tick in the settings area!!!

Not sure I understand the question. Are you asking what the effect of disabling UDP, TCP or ICMP ports are in general, or the specifics of diabling msmsgs?

Oops! 'Disabling msmsgs'

What does it do, remember in the firewall settings in the XP firewall

Process File: msmsgs or msmsgs.exe

Process Name: MSN Messenger Traybar Process

Description: MSN Messenger is an Online Chat and Instant Messaging Client

In other words, you have simply closed down the ports used by Windows Messenger. You can achieve the same effect by closing down or disabling the Windows Messenger service. As I have absolutely no need for either Windows Messenger or Messenger services, they are both set to Disabled on my main XP PC.

What is msmsgs? What happens if I disable it from accessing the internet?

It is the firewall that I have blocked some ports from accessing the internet. Now it says stealth where it said Closed before.

MSN Messenger opens 14 separate ports (see below). If you have closed them all, it will not work at all. If you have left the chat port open, you will still be able to chat, if you have left the video port open, you will still be able to video-conference, etc.

A port can still be open, but stealthed. Steve Gibson's site explains quite clearly what 'stealthed' means.

MSN Messenger requires TCP ports 1863, 5060, 1503, 3389, 6891, 6892, 6893, 6894, 6895, 6896, 6897, 6898, 6899 and 6900 to be open.
