`Modifying WINS server defaults
`
`Updated: January 21, 2005
`
`Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2, Windows Server 2008, Windows Server
`2008 R2, Windows Server 8 Beta
`Modifying server defaults
`WINS uses several default server configuration parameters that determine how NetBIOS name records are managed in the WINS server database. These parameters
`affect the default settings applied by each WINS server for any records stored locally.
`
`The following sections describe the default, minimum, and maximum settings that can be applied for database records. Included is the examination of behavior
`differences in servers running under each of the released versions of WINS. In most cases, default values are acceptable. In some cases, you might choose to modify
`the defaults to accommodate special circumstances, such as when a host name change must be made or when you renumber your network so that hosts use
`different IP addresses.
`
`All of these settings are configured on the Intervals tab of the WINS <Server name> Properties dialog box.
`Renew interval
`The WINS renew interval setting specifies how often a client renews registration of its names. The following table shows the supported range of values for Renew
`interval:
`
`
`5 hours ﴾Windows NT Server 3.5﴿
`
`Default:
`
`4 days/96 hours ﴾Windows NT Server 3.51﴿
`
`6 days/144 hours ﴾Windows NT Server 4.0, Windows 2000 Server, and the Windows Server 2003 family﴿
`
`Maximum:
`
`999 hours ﴾Windows NT Server 3.5, 3.51, and 4.0﴿
`
`365 days ﴾Windows 2000 Server and the Windows Server 2003 family﴿
`
`Minimum: 40 minutes ﴾all versions of Windows NT Server, Windows 2000 Server, and the Windows Server 2003 family﴿
`
`When adjusting this value from its service default, consider the following guidelines:
`
`
`Increasing the renew interval ...
`Causes client names to be renewed with WINS less often.
`
`Decreasing the renew interval ...
`Causes client names to be renewed with WINS more often.
`
`Reduces client registration activity and performance loads on the WINS server.

`
`Important
`
`Any changes made to the WINS renew interval also directly affect the extinction interval and extinction time‐out values, which are dependent on this setting.
`
`Extinction interval
`The WINS extinction interval specifies the time interval between when an entry is marked as Released and when it is marked as Extinct in the WINS database. The
`default value is dependent on the renew interval and, if the WINS server has replication partners, on the maximum replication time interval. The following table
`shows the supported range of values for Extinction interval:
`
`Default:
`
`﴾Dependent on Renew interval﴿
`
`Maximum:
`
`999 hours ﴾Windows NT Server 3.5, 3.51, and 4.0﴿
`
`365 days ﴾Windows 2000 Server and the Windows Server 2003 family﴿
`
`40 minutes ﴾Windows NT Server 3.5, 3.51, Windows 2000 Server, and the Windows Server 2003 family﴿
`
`Minimum:
`
`1 hour ﴾Windows NT Server 4.0﴿
`Extinction timeout
`The WINS extinction timeout specifies the interval between when an entry is marked extinct and when the entry is scavenged from the database. The default value
`is dependent on the renew interval and, if the WINS server has replication partners, on the maximum replication time interval. The following table shows the
`supported range of values for Extinction time‐out:

`Verification interval
`The WINS verification interval specifies the time after which the WINS server must verify that old names that it does not own are still active. The default is
`dependent on the extinction interval. The following table shows the supported range of values for Verification interval:
`
`Default:
`
