The version of the Microsoft DNS Server shipped with Windows 2000 is much improved over its Windows NT 4.0 predecessor when it comes to logging and debugging. Previous versions of the server were like a "black box" you couldn't see inside of. But now you can direct the server to write several different kinds of helpful logging and debugging information while it's running.
To enable this feature, right-click on a server in the left pane of the DNS console, choose Properties , then select the Logging tab. The window looks like the one shown in Figure 7-1.
