Backing Up and Restoring the WINS Database

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.

• You can use the ntbackup.exe utility to back up the WINS database. The Windows Server 2003 Volume Shadow Copy feature allows you to back up the WINS database while it is online. In previous Windows versions, you first had to stop the WINS service before you could start backing up the database.

• Back up the WINS database from the command-line, using the netsh.exe command line utility.

If you have backed up the WINS database, you can restore a previously backed up version when the existing WINS database becomes corrupt, or is lost.

• You can use the WINS console to restore a previously backed up WINS database.

• You can also use the netsh.exe command-line utility if you want to restore the database from the command-line.
