NetBIOS name resolution
NetBIOS name resolution means successfully mapping a NetBIOS name to an IP address. A NetBIOS name is a 16-byte address that is used to identify a NetBIOS resource on the network. A NetBIOS name is either a unique (exclusive) or group (nonexclusive) name. When a NetBIOS process is communicating with a specific process on a specific computer, a unique name is used. When a NetBIOS process is communicating with multiple processes on multiple computers, a group name is used.
An example of a process that uses a NetBIOS name is the File and Printer Sharing for Microsoft Networks service on a computer running Windows XP Professional. When your computer starts up, this service registers a unique NetBIOS name based on the name of your computer. The exact name used by the service is the 15-character computer name plus a 16th character of 0x20. If the computer name is not 15 characters long, it is padded with spaces up to 15 characters.
When you attempt to make a file-sharing connection to a computer by using its computer name, the File and Printer Sharing for Microsoft Networks service on the file server you specify corresponds to a specific NetBIOS name. For example, when you attempt to connect to a computer called CORPSERVER, the NetBIOS name corresponding to the File and Printer Sharing for Microsoft Networks service on that computer is:
