After you install Internet Information Services (IIS) 5.0, you may want to import a backup key file from an older version of IIS. This allows you to use the SSL capabilities on your new server (and replace the old one).

Note If you are upgrading the server to IIS 5.0, this should be done for you automatically. You will not need to export or import the private or public key pair from the older server.

Therefore, you do not need to run this tool on Web servers that are running IIS 6.0. However, if you are upgrading from a previous version of IIS, you should run the IIS Lockdown Tool before the upgrade to enhance the security of your Web server.
