What is the Windows NetBIOS Messenger service?
The Windows NetBIOS Messenger service is a component on Windows that primarily provides backward compatibility with previous versions of Windows, especially in enterprise networks. The Windows Messenger service, is also sometimes known as net send. Although the names are similar, this service should not be confused with the peer-to-peer Windows Messenger service, or MSN Messenger service, which are used for online chat.

Some spammers have used the Windows NetBIOS Messenger to send spam to unsuspecting users' machines, although most firewalls will prevent this kind of spam. Beginning with Windows XP Service Pack 2, this service is disabled by default, and for most consumer, and non-enterprise machines no functionality will be lost by disabling this service.
