Windows Live Messenger (original MSN) is closely associated with Windows systems, and they can share certain settings or directly correlate.
Configure browsers for Instant Messaging
To share activities or games in Windows Live Messenger, you need to make sure that the security settings in your browser allow scripts (a common programming task, connect existing program components to complete new related tasks), and cookies. Therefore, you need to configure your Internet Explorer.
To configure Windows Internet Explorer for Instant Messaging:
1, start Internet Explorer.
2, on the Tools menu, click Internet Options.
3, on the Security tab, click Internet, and then click Custom Level.
4. Under script, make sure all script options are enabled.
5, in the Reset to list, click Medium or Low, and then click OK.
6, on the Privacy tab, move the slider to Medium or higher, and then click OK.
Open a port in the firewall
You may need to configure your firewall (add "MSNmsgr.exe" to the list of allowed programs on your firewall) to allow Windows Live Messenger to access the Internet. For more information about how to add "MSNmsgr.exe" to the list of allowed programs, see your firewall documentation or Web site.
Attention
If your firewall or hardware does not support Universal Plug and Play (UPnP), which connects your computer to a common standard that is compatible with multiple network devices, manually enable outbound port 1863, which can sometimes help establish direct connections with some Microsoft. NET Messenger Service servers.
