256986 Description of the Microsoft Windows Registry

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: 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.

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. 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.
  2. Start Registry Editor.
  3. 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
  4. 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.
  5. Configure this for every push partner.NOTE: If "replicate only with partners" was not checked in step one then it would be possible for a server to pull records without being configured as a push partner. This is not a desirable situation since we can only control static record replication if the server is configured in the push partner list. Instead you need to configure these servers as push partners, even if they are currently only pulling.

  6. Quit Registry Editor.
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.
