www.BlackViper.com: Windows 7 Services 411 - TCP/IP NetBIOS Helper

TCP/IP NetBIOS Helper

Default Description:

Provides support for the NetBIOS over TCP/IP (NetBT) service and NetBIOS name resolution for clients on the network, therefore enabling users to share files, print, and log on to the network. If this service is stopped, these functions might be unavailable. If this service is disabled, any services that explicitly depend on it will fail to start.

Additional Information:

This feature provides legacy support for NetBIOS over TCP/IP. If your network does not use NetBIOS and/or WINS, disable this function.
