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 applica tions
such as FTP.
Advanc ed 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 b y
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”.
Advanc ed 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 compute r (node)
on the network. A computer typically registers itself when it starts.
Resolution is the process used to determine the specific address for a c omputer name.
RFCs 1001 and 1002 specify how NetBIOS should be implemented over TCP/IP
and define the name resolution modes.
