256986 Description of the Microsoft Windows Registry



SUMMARY
Some new registry entries are available for Windows NT 4.0.



MORE INFORMATION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

The registry path for these entries is the following:   HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\ Wins\ Parameters

BurstHandling Type = REG_DWORD Value: 0 or 1 Default = 0 This parameter is used to temporarily achieve a steady state in the WINS server when the WINS server is either started with a clean database or many WINS clients come online for the first time. Either situation causes a large amount of name registration and name refresh traffic to occur. The WINS server currently stores a maximum of 25,000 name registration and refresh queries in its queue before dropping queries. By using this parameter, the WINS server can be configured to send success responses to the clients whose requests are dropped. These response will have time-to- live (TTL) values that will slow down the refresh rate of those WINS clients and regulate the burst of WINS client traffic. This will result in a steady state being reached much more quickly.

To turn on this parameter, change the value to 1.

The ConsistencyCheck Subkey
This is an optional subkey that should be created if you want WINS to periodically perform database consistency checks. To create this subkey, start Regedt32.exe and go to the following key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Wins\Parameters

Create a new value named ConsistencyCheck. Once this key has been created, you can add the following values:

MaxRecsAtATime

Type = REG_DWORD

Range = 1000 to total number of records (decimal)

Default = 30000

Specifies the maximum number of records that will be replicated in one consistency check cycle. WINS does consistency checks on the records of each owner WINS server (the WINS server from which the record was replicated). After checking an owner WINS server, the local WINS server continues to the next owner WINS server, or stops. This is determined by the MaxRecsAtATime value.   UseRplPnrs Type = REG_DWORD or nonzero value Range = 0 or nonzero Default = 0 If set to zero, WINS will contact the owner WINS server. If set to a nonzero value, WINS sill contact only its pull partners to perform consistency checks. If set to nonzero, WINS randomly picks a WINS from its list of pull partners unless the owner WINS server also happens to be a pull partner. In that case, the owner WINS is contacted.   TimeInterval Type = REG_DWORD Range = 21600 (6 hours) - entered in seconds (decimal) Default = 86400 (24 hours) - entered in seconds (decimal) Specifies the time interval between WINS server database consistency checks.   SpTime Type = REG_SZ Default = 2:00:00 (2 A.M.) Specifies the specific time at which the first WINS server database consistency check will occur. The time is specified in hh:mm:ss format. Thereafter, the WINS database is periodically checked for consistency by using the time interval specified in the TimeInterval parameter.
