Messenger problems: Configuring your firewall

17 July 2009 by J.M.

Windows Firewall A lot of connection problems of all kinds will raise if you are using a firewall that does not allow Windows Live Messenger to connect to the MSN servers. Here are some key tips on which communication needs to be allowed and white-listed so that Messenger can sign in properly.

The following ports are used by Messenger:

  • TCP 443
  • TCP 1863
  • TCP 80.

There are two kinds of firewalls:

  • software firewalls, like Windows Firewall, and
  • hardware firewalls. If you are using a router to connect to the web, it has probably such a firewall.

Configuring Windows Firewall for Messenger

  • Click Start, Control Panel.
  • Choose Windows Firewall.

  • Allow a program or feature through Windows Firewall If you are using Windows Vista or Windows 7, click the link Allow a program or feature through Windows Firewall.
  • In the appearing Windows Firewall dialog, switch to the Exceptions tab. If you are using Windows 7, click the button Change settings.
  • Now add an exception for the following file:
    C:Program FilesWindows LiveMessengermsnmsgr.exe
    If you are using a 64-bit version of Windows, the path starts with C:Program Files (x86).

If these steps do not fix your problem, Internet Explorer Offline mode might be the bad guy. In my next post, I will show you how to fix this issue.
