In this lab, you will create an application that uses the thread pool to queue up methods to call on separate threads. If you encounter a problem completing an exercise, the completed projects are available on the companion CD in the Code folder. 1. Create a blank console application with the name ThreadPoolDemo. 2. Include (or import for Visual Basic) the System.Threading namespace. 3. Create a new method to simply display some text. Call it ShowMyText. Accept one parameter of type object, and call it state. 4. Create a new string variable inside the ShowMyText method, and cast the state parameter to a string while storing it in the new text variable. 5. Inside the ShowMyText method, write out the ManagedThreadId of the current thread and write the new string out to the console. 6. In the Main method of the console application, create a new instance of the WaitCallback delegate that refers to the ShowMyText method. 7. Use the ThreadPool to queue up several calls to the WaitCallback delegate, specifying different strings as the object state. Your code might look something like this:

Practice 1: Download and install the network package of the latest service pack for Windows XP Professional. Extract the package and run Update.exe with the - switch, and then review the available command-line switches. Use the appropriate command-line switches to perform an unattended installation. Then, uninstall the service pack by using Add Or Remove Programs. Practice 2: Using an unpatched Windows XP Professional installation, use Internet Explorer to visit the Microsoft Windows Update site at http://windowsupdate .microsoft.com/. Choose to perform a custom installation of the available patches and explore each of the available updates to understand what changes they make. Bring your Windows XP installation up-to-date by installing the latest service packs and all available critical updates. Practice 3: Use the Microsoft Baseline Security Analyzer, available from http:// www.microsoft.com/technet/security/tools/mbsahome.mspx, to identify any computers on your network that are missing critical updates. Practice 4: Install Microsoft Software Update Services (SUS), available from http://www.microsoft.com/sus/ on a Windows Server 2003 computer. Configure Automatic Updates on a Windows XP Professional computer to retrieve updates directly from SUS. Be familiar with how to configure Automatic Updates for Windows XP Professional stand-alone computers and members of an Active Directory domain. Practice 5: If you have time, install Windows XP Professional on a computer, but do not activate it. Wait until the 30-day grace period expires, and note the limited functionality that Windows XP provides you until you have activated it.

The internal interface of the ISA Server computer should be configured with a DNS server address that can resolve internal host names. When incoming requests from external clients are forwarded to the internal network, the ISA Server computer will use the DNS server configured on the internal interface to resolve the internal host name. This is especially important if you choose to use host names when publishing internal servers using Web publishing rules.
