Preventing WINS Static Record Replication

ID: Q229897

The information in this article applies to:
  • Microsoft Windows NT Server version 4.0
IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SUMMARY

This article describes how to use the OnlyDynRecs registry value to prevent Windows Internet Name Service (WINS) static records from replicating to replication partners.


MORE INFORMATION

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

You can use WINS to add static records in the WINS database. Typically, static records are difficult to remove from a network of WINS servers and are useful only on the server to which a static record is added.

To prevent static record replication:

  1. Start Registry Editor.


  2. Locate the following registry key:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wins\Partners\Push\partner IP address\OnlyDynRecs

    Data Type : REG_DWORD
    Range : 0 or 1
    Default : 0


  3. Set the range to 1. This specifies that only dynamically registered records are replicated to WINS pulling replicas. The default setting of 0 specifies that all records (dynamic and static) are replicated.


  4. Configure this for every push partner, and every partner that pulls records from the configured server. This includes partners that only pull records from the configured server and are not currently configured as push partners. You need to configure these servers as push partners, even if they are currently only pulling.


  5. Quit Registry Editor.


  6. On the server you are configuring to not replicate static records, choose the "Replicate Only with Partners" option on the Advanced tab of the WINS server Configuration tool. This prevents unintended replication of static records from a server that is not configured as a replication partner.


When a WINS server pulls from another server (either on its own or after being triggered by a push notification from another server), the WINS server checks the remote server's push partner registry key for the OnlyDynRecs value. If the OnlyDynRecs value is set to 1, the pulling partner does not process static records. If the OnlyDynRecs value is set to 0 or if it is not found, static records are processed.
