In August 2004, Microsoft released a free update to Windows XP that includes a number of new enhancements that make Windows XP an even better operating system for mobile PCs. These enhancements include: Security improvements. One of the main focuses of SP2 is security. The following improvements make Windows XP a more secure operating system: Windows Security Center is a central place for you to view your security settings and learn more about how to improve the security of your computer with Windows Firewall, Automatic Updates, and antivirus software. Windows Firewall is now automatically enabled and helps protect your computer against viruses and other security threats, such as intruders who might try to access your computer over the Internet.

When you install ISA Server, you have the option of installing the Firewall Client Share on the ISA Server computer. When you choose this option, the Firewall Client installation files are copied to the server in the C:\Program Files\Microsoft ISA Server\Clients folder. The folder is then shared with a share name of Mspclnt. Moreover, the system policy rule that enables access to the shared folder is enabled. To install the Firewall Client manually, users can connect to the share and run the setup program.

In this practice, you will create and then locate objects in Active Directory. You will create OUs, users, groups, and computers. You will then create a saved query and customize the view of that saved query. The objects you create in this practice will be used in other practices in this training kit. Exercise 1 Create Organizational Units The default Users and Computers containers are provided to facilitate the setup of and migration to an Active Directory domain. It is recommended that you create OUs that reflect your administrative model and that you use these OUs to create and manage objects in your directory service. In this exercise, you will create OUs for the example domain, contoso.com. These OUs will be used in practices and exercises later in this training kit. 1. Log on to SERVER01 as Administrator. 2. Open the Active Directory Users And Computers snap-in. 3. Expand the Domain node. 4. Right-click the Domain node, choose New, and then select Organizational Unit. 5. Type the name of the organizational unit: People. 6. Select Protect Container From Accidental Deletion. 7. Click OK. 8. Right-click the OU and choose Properties. 9. In the Description field, type Non-administrative user identities. 10. Click OK. 11. Repeat steps 2 10 to create the following OUs.

Having enough free space on the volume to install the operating system is one thing, but you will need space for an office productivity suite, all that e-mail that arrives, and space to install the latest and greatest games. Although a standard Windows Vista installation will consume approximately 7 GB of hard disk drive space, the recommended minimum amount of hard disk drive space is 20 GB, and the recommended amount is 40 GB. If you had only 7 GB of hard disk drive space, you would not be able to install any extra applications!

Tony Northrup Years ago, I used to recommend that everyone install IIS, enable the SMTP service on the computer that would be running their application, and send messages through the local SMTP server. This process is much more efficient than using a remote SMTP server because the local IIS SMTP server will directly contact each recipient s SMTP servers to send the message. Additionally, you don t have to deal with network connections. However, this approach became unreliable as organizations battled against spam. Organizations now block incoming messages from large blocks of IP addresses. Even if you are not a spammer, messages sent from a local SMTP server might be rejected if your IP address appears on one of these lists. To make it more complicated, you might be able to send messages to most domains but be rejected by others. Ultimately, the job of managing SMTP servers is now too complex to have every user running their own mail server. As a result, I now recommend people use their ISP s or their organization s mail server for outgoing messages.
