|
|
those produced by SMB/CIFS clients such as Windows 95/98/ME,
|
|
Windows NT, Windows 2000, Windows XP and LanManager clients. It also

participates in the browsing protocols which make up the

Windows "Network Neighborhood" view.</P

listen for such requests, and if its own NetBIOS name is

specified it will respond with the IP number of the host it
|

is running on. Its "own NetBIOS name" is by

default the primary DNS name of the host it is running on,
