Using the Registry
You can specify that static mappings be treated as dynamic during the replication process by
creating or modifying the following Registry value:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wins\Parameters\]
"MigrateOn"=dword:1
You can specify the time interval, in seconds, at which the WINS server announces its
presence through multicast announcements, by creating or modifying the following Registry
value:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wins\Parameters\]
"McastIntvl"=dword:
<Interval>
Specify
<Interval>
with a minimum value of 2,400 seconds, or 0x960 in hexadecimal format.
You can enable automatic partner configuration by creating or modifying the following
Registry value:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wins\Parameters\]
"UseSelfFndPnrs"=dword:1
You can specify that only dynamic records are replicated by creating or modifying the
following Registry value:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wins\Parameters\Push\
➥
<IPAddress>
]
"OnlyDynRecs"=dword:1
How It Works
You can configure your WINS server to automatically configure other WINS servers as repli-
cation partners using broadcast-and-discover functionality.
WINS servers periodically announce themselves using Internet Group Membership Protocol
(IGMPv3) messaging on a standard address of 224.0.1.24. When you have enabled your WINS
server to automatically configure other servers as replication partners, you have effectively
configured your server to listen for these announcements, and when found, to configure the
remote server as a replication partner. In addition, the server will be configured as both a push
and a pull partner with pull replication set to occur every two hours.
Here are some important notes:
Automatically configured partners will remain as partners only as long as WINS runs.
If the service stops cleanly (perhaps because the server shuts down), the replication
partners will be removed. The partners will be added again when the service restarts,
generating a constant cycle of additions and removals. To enable persistent replication
partner configuration, you should add the partners manually rather than rely on the
automated process.
The automated announcement and discovery process generates a significant amount of
network traffic. This process is therefore recommended only for small networks containing
a single subnet with one to three WINS servers.
