The .NET Messenger Service (often referred to colloquially as MSN) is an instant messaging and presence system developed by Microsoft. Its authentication system allows anyone with an e-mail address that is registered as a Windows Live ID to sign in and communicate with other people who are signed into the network. The service can also integrate with Microsoft's Windows operating system, automatically and simultaneously signing into the network as the person logs into Windows.

Disambiguation

Windows NT Messenger Service

Windows NT and newer operating systems from Microsoft included a system notification service called "Messenger Service", which was intended for use within workgroups, but eventually became used maliciously to present pop-up advertisements to users. This service, although it has a similar name, is not related in any way to the .NET Messenger Service or the Windows Messenger instant messaging client. It became disabled by default with Windows XP Service Pack 2 and Windows Server 2003 Service Pack 1 and was removed completely in Windows Vista and Windows Server 2008.

Microsoft .NET Framework

Despite its name, the .NET Messenger Service is not in any way related to the Microsoft .NET Framework development platform. Neither the official clients nor the protocol itself is tied to the .NET Framework.
