  1. From the Start menu, point to Programs, point to Administrative Tools, and then click Internet Services Manager.
  2. Under the Tree pane, browse to the desired Web site.
  3. Right-click the Web site, and then click Properties.
  4. On the Directory Security tab, under Anonymous access and authentication control, click Edit.
  5. Select (and implement) at least one type of authentication method.
