The new Windows 2000 exams are quite a different animal from the connect the dots and recall the definitions type questions we saw in the Windows NT 4.0 exams. In the Windows 2000 version, you'll be expected to take the knowledge you have about a particular technology and apply that knowledge in solving vexing troubleshooting scenarios.
Let's take a look at the type of problem you might run into on the Windows Network Infrastructure exam 70-216.
The Riddle of the Disappearing NetBIOS Resources
You have been called to solve a problem with your WINS replication network. Your network spans several subnets, and contains a variety of network client and server operating systems, including Windows for Workgroups, Windows 95, Windows 98, Windows NT 4.0, Windows 2000 and UNIX. All the host systems either share or access NetBIOS resources on other machines on the network.
Static WINS database entries have been made for the UNIX systems, and these UNIX systems use WINS Proxy Agents to access information in the WINS database. All the machines on the network use DHCP, except a handful of Windows-based Servers and the UNIX hosts.
You have been running the UNIX based systems mainly to take advantage of a rare NetBIOS application that had not been ported to Windows 2000. Now that the application is available on the Windows 2000 platform, you wish to upgrade to Windows 2000.
The upgrade process goes smoothly, and the applications install without any serious incidents. You disable all the WINS Proxy Agents on the network to reduce NetBIOS traffic and the load on the WINS Servers, and you configure the former UNIX machines to be WINS and DHCP Clients.
Later in the day, you start receiving calls from users telling you that they cannot access any NetBIOS resources on the machines that have been upgraded. When investigating the problem, you observe what is seen in the following screen shots.
With this information, what do you believe is causing the problems with this network?
Rather than giving you the multiple choice answers now, I want you to do some research on WINS. Notice that you are presented with several Properties dialog boxes from the WINS Console. Do all of them have relevance? Do some of them? Do any of them? You need to think about whether these graphics are being used to throw you off-course, or if they contain the nugget of truth that will solve the problem.
Think about NetBIOS hosts, non-NetBIOS Hosts, and the WINS database. What are some of the special circumstances that might arise in such an environment? What are the special troubleshooting considerations that come into play when such an environment has been upgraded?
Many of the questions you will encounter are troubleshooting based questions. That's why we recommend our Troubleshooting Windows 2000 TCP/IP as your last, best hope of passing this very difficult exam. If you have read the book, then you already know the answer!
