IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base:

256986 Description of the Microsoft Windows Registry


You can configure WINS to pull or push only special groups (Internet Groups) and domain<0x1B> names. This article describes how to configure specific domains to replicate WINS databases.


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.

A domain<0x1B> name is a unique multi-homed name registered by the Primary Domain Controller (PDC) of each domain.

Internet Groups are user defined groups that store up to 25 members.
By default a space character (0x20) is appended to the Internet group name as the 16th byte.

You can configure WINS servers to replicate only domain<1B> names or Internet group names. This can be useful if you need to replicate names relevant to certain DNS domains.
Domain specific information would not need to be replicated to other WINS servers. Only 1B names and user defined groups would need to be replicated to allow a client to query its WINS server to get information(DCs and members in user defined Internet groups) that spans multiple DNS domains, one or more of which are serviced by other WINS servers.

In order to configure this on the WINS server, use Registry Editor to add the following registry key:


Add the following value to the registry key listed above:

   Value Name: ReplicationType
   Data Type:  REG_DWORD
   Value:      1

The registry value in this article applies to replication with all Pull and Push partners of the local WINS server. In order to apply this to all its Pull partners only, add the above registry value under the following key:


In order to apply this to all its Push partners only, add the above registry value under the following registry key:


In order to apply this to a specific Pull partner only, add the above registry value under the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WINS\Partners\Pull\<IP address of pull partner>

In order to apply this to a specific PUSH partner only, add the above registry value under the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WINS\Partners\Push\<IP address of push partner>

If the parameter is specified in more than one place, the lower one in the key hierarchy supersedes the key above it. The default value of this parameter is 0 which means "replicate all records".

The replication protocol has been enhanced so that a partner can communicate its desire for a subset of records (replication type) to the WINS server it wants to pull from. The WINS that is sending records uses the replication type specified for that partner unless it indicates default replication (replicate all records) in which case it uses the replication type specified by the pulling WINS server. When the "pulled from" WINS server is not running Windows NT version 4.0 or later, it ignores the desired replication type of the partner and sends all records. The pulling WINS then sifts through the records and stores only those that are wanted in its database.

CAUTION: Use this feature of WINS only if it is absolutely necessary. Databases can become out of synchronization when you apply this registry key value.
