    in order to have better security, i block msn messenger with my router, but seems that it fails:

    Router: Linksys WRT54G
    Firmware Version: v3.01.3
    i go to Access Restrictions, and set the status to "enable"

    Edit list of PC: i put pcs' ip here, IP:, then choose "Allow" (DHCP: start from, 15users)
    Days: Everyday
    Times: 24hrs

    Block services: (the ports which i want to block are as below)

    After those setting, i save it with clicking "SAVE SETTING".

    After these setting, i found that the msn messenger is stilling working, what should i do if i want to disable msn?

    Thanks & Regards,

    Blocking ports on your router does not mean programs won't run on your computer. Windows Messenger and MSN Messenger are tied to Outlook and Outlook Express so when you run these programs Messenger will also load.

    Download and run this.

    If you are running Norton AntiVirus, you may also need to disable Instant Messenger Protection for MSN Messenger as a service.

    you probably have upnp on your router and msn senses that there is no port for it to go through so it asks (politely) for the upnp service to open one and it does. i dont think there is a good way to stop upnp and not ruin everything else.

    there are ways to do it but im not sure what they are.
    how many messenger servers are there like the Blue.oscar.aol.com
    ones used for AIM if there arent many you could just refuse access to them.

    but there is no way to block msn really. if a user wants to use it they will go through an externam proxy server and then what?
    i assume this is a work environment? so you really cant stop people from doing things while you arent there.

    What operating system are you running on your computers?

    Why not just uninstall it? Someone must have installed it manually since it is not part of Windows.

    Esquire, i know "uninstall" is a solution, but not safety if users re-install it again.
    so i would like to block any non-used ports.

    Which was why I asked what operating systems you are currently using.

    Esquire, we are using Windows XP Pro

    Since you are using 2000/XP, I presume your users are using their own user accounts to log on to Windows, right? You can remove everyone else from having administrator privilege after you have uninstalled MSN and Windows Messengers. They won't have any right to install/uninstall anything thereafter (except the person with the Administrator account) - that is one of the beauties of using Windows 2000/XP in a corporate environment.
