● DNS name resolution
The Domain Name System (DNS) provides a way to look up name mappings when
connecting a computer to foreign hosts using NetBIOS over TCP/IP or applications
such as FTP.
Advanced Server does not use this method.
● An LMHOSTS/ names.cfg file to specify the NetBIOS computer name and IP address
mappings, or a HOSTS file to specify the DNS name and IP address.
On a computer running Microsoft networking components, the HOSTS file (used by
Windows Sockets applications to find TCP/IP host names) and LMHOSTS file (used by
NetBIOS over TCP/IP to find Microsoft networking computer names) can be used to list
known IP addresses mapped with corresponding computer names. LMHOSTS is used
for name resolution for small-scale networks or remote subnets where WINS is not
available. For more information about the LMHOSTS file, see Windows NT Help and
the
Microsoft Windows NT Resource Kit Networking Guide .
On a computer running Advanced Server, a names.cfg file can be used in a way compa-
rable to the LMHOSTS file, see section “The names.cfg file” .
Advanced Server networking components never use HOSTS files for name
resolution.
10.1.1 NetBIOS over TCP/IP (NetBT) Name Resolution
NetBIOS over TCP/IP (NetBT) is the session-layer network service that performs name-to-
IP address mapping for name resolution. In Advanced Server, NetBT name resolution is
implemented through WINS, broadcast name resolution and the optional use of a
names.cfg
file containing static name-to-IP-address mappings.
The two most important aspects of the related naming activities are registration and
resolution :
● Registration is the process used to register a unique name for each computer (node)
on the network. A computer typically registers itself when it starts.
● Resolution is the process used to determine the specific address for a computer name.
RFCs 1001 and 1002 specify how NetBIOS should be implemented over TCP/IP
and define the name resolution modes.
