Windows Internet Name Server (WINS) Overview
WINS is an enhanced NetBIOS name server (NBNS) which was designed by Microsoft to resolve NetBIOS computer names to IP addresses, and at the same time eliminate the usage of broadcasts for name resolution. In this manner, WINS eliminates traffic generated by broadcasting on the network.

WINS Server Role Security Issues
A WINS server is an enhanced NetBIOS name server that can resolve NetBIOS computer names to IP addresses. The WINS database hosted on the WINS server is used to store and maintain NetBIOS computer names to IP addresses mappings.

Using System Monitor to Monitor WINS Activity
The System Monitor utility is the main tool for monitoring system performance. System Monitor can track various processes on the Windows system in real time. The utility uses a graphical display that you can use to view current data, or log data.

Protecting the WINS database
To protect your WINS databases from disasters and corruption, you should regularly back up your WINS databases.
The methods which you can use to back up the WINS database are:

You can use the WINS console to perform:

A manual back up of the WINS database

Schedule an automatic backup of the WINS database.

In the Windows Server family, the primary means for client computer to locate and communicate with other computers on a internet Protocol (IP) network is by using Domain Name System (DNS). However, clients that use older versions of Windows, such as Windows NT 4.0, use network basic I/O system (NetBIOS) names for network communication.

WINS replication is the process of copying updated WINS data from one WINS server to other WINS servers in a network to synchronize the data.
Replication of WINS databases ensures that a name which is registered with one server gets replicated to other WINS servers on the network.

If you are unable to repair a corrupt database that has been caused by a system failure, a virus attach, a power failure, or a similar disaster, you can first delete the WINS database and then entirely restore it from a backup. The WINS management console is a comprehensive tool which can be used to plan and perform a WINS database backup.
