Managing Static NetBIOS-to-IP Address Mappings (Solaris PC NetLink 1.0 Administration Guide)

Solaris PC NetLink 1.0 Administration Guide

Managing Static NetBIOS-to-IP Address Mappings

Static mappings are non-dynamic database entries of NetBIOS computer name-to-IP address mappings for computers on the network that are not WINS-enabled or for special groups of network devices.

Use the Static Mappings command on the Mappings menu in WINS Manager to view, add, edit, delete, import, or filter static mappings.

Once a static name-to-IP address mapping is entered into the WINS server database, it cannot be challenged or removed except by an administrator who must remove it manually using WINS Manager. All changes made to the WINS server database using WINS Manager take effect immediately.

Note -

A DHCP reserved (or static) IP address for a unique name in a multihomed computer overrides an obsolete WINS static mapping if the WINS server advanced configuration option Migration On/Off is checked On.

Static NetBIOS name mappings can be any of the types listed in the following table.

Table 5-4 Static NetBIOS Name-Mapping Types


Type Option	Description
Unique	A unique name that maps to a single IP address. Contrast with multihomed type.
Group	Also referred to as a "Normal Group." When adding an entry to Group using WINS Manager, you must enter the computer name and IP address. However, the IP addresses of individual members of Group are not stored in the WINS database. Because member addresses are not stored, there is no limit to the number of members that can be added to a Group. Broadcast name packets are used to communicate with Group members. Contrast with Internet group type.
Domain	A NetBIOS name-to-IP address mapping that has 0x1C as the 16th byte. A domain group stores up to a maximum of 25 addresses for members. For registrations after the 25th address, WINS overwrites a replica address or, if none is present, it overwrites the oldest registration.
Internet group	Internet groups are user-defined groups that allow you to classify resources such as printers for easy reference and browsing. The default 16th byte of an Internet group name is set equal to 0x20. An Internet group can store up to a maximum of 25 addresses for members. When you add an Internet group, three unique records are added: `InternetGroupName<0x20>` `InternetGroupName<0x3>` `InternetGroupName<0x0>` This is similar to the domain group. Internet group members can be added as the result of dynamic group registrations. However, a dynamic member does not replace a static member that is added by using WINS Manager or by importing the `LMHOSTS` file. Contrast with Group type.
Multihomed	A unique name that can have more than one address. This is used for multihomed computers. The maximum number of addresses that can be registered as multihomed is 25. For registrations after the 25th address, WINS overwrites a replica address or, if none is present, it overwrites the oldest registration. Contrast with Unique type.

You can configure a WINS server to replicate only domain, Internet, and multihomed group to its replication partners, by manually changing the Replication Type Registry parameter to a value of 1.

This procedure eliminates the replication of information (unique names) that is not needed outside the local domain, while allowing replication of special group information. When a group spans multiple domains that are serviced by other WINS servers, it is desirable to reduce replication traffic

Table 5-5 Basic WINS Server Statistics Descriptions


Statistic	Description
Server Start Time	The time when this WINS server was started.
Database Initialized	The last time static mappings were imported into the WINS database.
Statistics Cleared	The time when statistics for the WINS server were last cleared with the Clear Statistics command from the View menu.
Last Replication Times	The times at which the WINS database was last replicated.
Periodic	The last time the WINS database was replicated based on the replication interval specified in the Preferences dialog box.
Admin Trigger	The last time the WINS database was replicated because the administrator chose the Replicate Now button in the Replication Partners dialog box.
Net Update	The last time the WINS database was replicated as a result of a network request, which is a push notification message that requests propagation.
Total Queries Received	The number of name query request messages received by this WINS server. Successful indicates how many names were successfully matched in the database, and Failed indicates how many names this WINS server could not resolve.
Total Releases	The number of messages received that indicate a NetBIOS application has shut itself down. Successful indicates how many names were successfully released, and Failed indicates how many names this WINS server could not release.
Total Registrations	The number of messages received that indicate name registrations for clients.

You can display additional statistics by clicking Detailed Information on the Server menu. The following table describes these detailed information statistics.

Extinction	The time when the database was last cleaned based on the Extinction interval specified in the WINS Server Configuration dialog box
Verification	The time when the database was last cleaned based on the verify interval specified in WINS Server Configuration dialog box
Unique Registrations	The number of name registration requests that have been accepted by this WINS server
Unique Conflicts	The number of conflicts encountered during registration of unique names owned by this WINS server
Unique Renewals	The number of renewals received for unique names
