Names registered by the WINS server can be divided into three groups:
- Computer Name
- Domain Name
- Other/Special Names
Each WINS Client actually registers its name with the WINS Server three or
: The MS-DOS clients that ship with Windows NT version 3.5 (LAN
Manager version 2.2c client for MS-DOS and Microsoft Network Client
version 3.0) provide support for WINS resolution, but not registration.
Several special NetBIOS names are also registered to maintain and retrieve
browse lists. Names listed here are indicated by "Name(xx)" name followed
by the hex value (xx) and padded with spaces to the 16th byte.
Registered Computer Names:
This name is registered for the WINS Client Workstation name.
This name is registered for the Messenger Service on the WINS.
Network monitoring utility (group name, registered when running netmon)
This name is registered for the Network Monitoring Agent service and
will only appear if the service is started on the system. If the
computer name is not a full 15 characters, the name will be padded with
plus (+) symbols.
Network monitoring agent (unique name, registered when remote agent is
This name is registered for the Network Dynamic Data Exchange (NetDDE)
services and will only appear if the NetDDE services are started on the
system. By default, under Windows NT version 3.5, the NetDDE services
are not automatically started.
This name is registered for the Server Service on the WINS Client.
RAS server service.
Registered Domain Names:
This instance of the domain name is registered by the Workstation so
that it can receive browser broadcasts from LAN Manager-based systems.
This is the name to which server announcements are broadcast in
Microsoft LAN Manager so that other Microsoft LAN Manager computers can
track the servers on the network. Windows computers do not make
these broadcasts unless the LMAnnounce option has been enabled by
configuring the Server service in the Control Panel/Networks
This instance of the domain name is registered by the Windows NT Server
system that is running as the Domain Master Browser and is used to
allow remote browsing of domains. When a WINS Server is queried for
a WINS Server returns the IP address of the system that registered this
This name is registered for use by the domain controllers within the
domain and can contain up to 25 IP addresses. One IP address will be
that of the Primary Domain Controller (PDC) and the other 24 will be
the IP addresses of Backup Domain Controllers (BDCs). The [1Ch] domain
name is used by the BDCs to locate the PDC and is used when pass-
through authentication is needed to validate a logon request.
This instance of the domain name is registered only by the Master
Browser, of which there can only be one for the domain. This name is
used by the Backup Browsers to communicate with the Master Browser in
order to retrieve the list of available servers from the Master
This name is registered by all Browser servers and Potential Browser
servers in a domain or workgroup. It is used for announcement requests
which are sent by Master Browsers to fill up its browse lists, and for
election request packets to force an election.
In addition to computer names and domain names, the following names also
appear in the WINS database.
This name is registered by the Master Browser and is used to broadcast
and receive domain announcements on the local subnet. It is through
this name that Master Browsers for different domains learn the names of
different domains and the names of the Master Browsers on those
domains. When a WINS Server receives a name query for this name, the
WINS Server will always return the subnet broadcast address for the
requesting client's local subnet.
When viewing the WINS database, the usernames for the currently logged
on users will also be registered in the WINS database. The username is
registered by the Server component so that the user can receive any
'net send' commands sent to their username.
