WINS

WINS registration can be added to your failover and failback scripts by using the Windows NETSH command with the WINS add name context. Add the following command to your failover and failback scripts for each additional WINS server in your environment (excluding the target’s primary WINS server).

netsh wins server wins_server_IP_address add name Name=source_server_name RecType=1 IP={IP_address}

Variable	Description
wins_server_IP_address	The IP address of the WINS server
source_server_name	The name of the source server
IP_address	The IP address of the target that has taken over for the failed source (for the failover script) or the IP address of the source that is reassuming its original identity (for the failback script)

For example, suppose you had the following environment.

• Source name—Alpha
• Source IP address—192.168.1.108
• Target name—Beta
• Target IP address—116.123.2.47
• Target’s Primary WINS server—116.123.2.50 
• First secondary WINS server on the network—192.168.1.110
• Second secondary WINS server on the network—150.172.114.74

You would add the following to your failover script to register the source’s name with the target’s IP address on the two secondary WINS servers.

netsh wins server 192.168.1.110 add name Name=Alpha RecType=1 IP={116.123.2.47} netsh wins server 150.172.114.74 add name Name=Alpha RecType=1 IP={116.123.2.47}

You would add the following to your failback script to register the source’s name back with the source’s original IP address on the two secondary WINS servers.

netsh wins server 192.168.1.110 add name Name=Alpha RecType=1 IP={192.168.1.108} netsh wins server 150.172.114.74 add name Name=Alpha RecType=1 IP={192.168.1.108}

See your Windows documentation or the Microsoft web site for more details on the NETSH command.

WINS replication can be added to your failover and failback scripts by using the Windows NETSH command with the WINS set replicate context. Add the following command to your failover and failback scripts.

netsh wins server target’s_primary_wins_server_IP_address set replicateflag 1

Variable	Description
target's_primary_wins_server_IP_address	The IP address of the target's primary WINS server

For example, suppose you had the following environment.

• Source name—Alpha
• Source IP address—192.168.1.108
• Target name—Beta
• Target IP address—116.123.2.47
• Target’s Primary WINS server—116.123.2.50
• First secondary WINS server on the network—192.168.1.110
• Second secondary WINS server on the network—150.172.114.74

You would add the following to your failover script to force the target’s primary WINS server to replicate its updated information to the other secondary WINS servers on the network.

netsh wins server 116.123.2.50 set replicateflag 1

You would add the same line to your failback script to force the target’s primary WINS server to replicate its updated information again. This would replicate information for the source’s name and the source’s original IP address to the other secondary WINS servers on the network.

netsh wins server 116.123.2.50 set replicateflag 1

See your Windows documentation or the Microsoft web site for more details on the NETSH command.
