Windows Name Resolution with the AVM Access Server
98 AVM Access Server – 5 AVM Access Server Concepts and Functional Principles
Dynamic Name Resolution using WINS
The static LMHOSTS file is not practical in networks in which
computers’ IP addresses or names change frequently (due to
dynamic IP address assignment by DHCP, for example). For such
cases Microsoft has developed the Windows Internet Naming
Service (WINS). WINS is an integral part of Windows NT and 2000
servers, and can be installed as an additional network
component.
WINS automatically creates a database in which all computers in
the network can register their names and current IP addresses.
Name resolution is then performed by sending a query to the
WINS database. In order for a computer to use the WINS service,
the IP address of the network’s WINS server must be entered in
the IP settings of the network adapter.
Because name resolution no longer requires broadcasts, but only
a query addressed specifically to the WINS server, WINS name
resolution can be used in routed networks and over dial-up and
VPN connections.
WINS and Remote Access with NetWAYS/ISDN
NetWAYS/ISDN clients that access the company LAN over direct
dial-in connections are automatically provided with the IP
address of the WINS server that is specified in the IP settings of
the AVM Access Server computer. The remote clients then register
automatically with the WINS server and can use its name
resolution service.
The IPsec specification does not provide a mechanism to pass
WINS server address on initiating a VPN connection, however. For
VPN connections, the WINS server address can be entered
statically in the IP settings of the NetWAYS/ISDN adapter. Note
however that the IP address of the WINS server must be in the IP
network defined for the VPN tunnel. Otherwise the WINS queries
would not be transported over the VPN.
NetBIOS name resolution can also take place using the DNS. DNS
server addresses can be passed to the remote site on initiating a
VPN connection. Because NetBIOS name resolution over DNS is
only possible in a pure Windows 2000 and XP environment, and
requires an appropriate DNS server configuration, the details are
beyond the scope of this manual.
