The Windows Server 2003 Microsoft DNS Server is much improved over its predecessors 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 Debug Logging tab. The window looks like the one shown in Figure 7-1.
