Most laptops have an Ethernet network port. With this port, you can connect your laptop to a network or another computer through an Ethernet cable. Your computer might also have a modem port, which you can plug a telephone line into, and then connect to the Internet, assuming you have an account with an Internet Service Provider (ISP). Both ports look very similar, so if you re unable to connect to your network or modem, verify that the cable is plugged into the right socket.

ass deployments of new operating systems or applications often have repercussions that haunt you long after all of the immediate technical problems

At present, each winery maintains its own Microsoft Access database to store all busi ness information. At the end of every quarter, this information is brought to the cen tral office and is transferred into the databases shown in Table 13-1:

In the event of a disaster, each Exchange Server role needs to be recovered in a different way. Being able to recover a server role requires knowing which aspects of the role need to be backed up. Each server role requires a separate backup strategy because each server role stores critical data in a different location. Some roles store most of their critical data within Active Directory, and others store all critical data locally. 12, Configuring Disaster Recovery, covered the technical details of how to back up important data. This lesson focuses more directly on the specific items that you need to ensure are backed up so that you can fully recover each server role in the event that there is a complete server failure.

You can export data from Windows Contacts using only two formats, CSV and vCards. When you perform an export, all your contacts are exported. You should export using the CSV format when you want the person with whom you are sharing your contacts to have access to all of your contacts. You should export using the vCard format when you want to be more selective about which contacts you want to share. Exporting using vCard format will provide you with a folder full of vCards, one for each contact. You then copy the ones you want to share and give them to the person you want to share them with. It is not possible to export a group contact to CSV or vCard format.

Windows Hardware Quality Labs (WHQL) tests and that have not been altered or overwritten by any program s installation process.

1. Correct Answer: A A. Correct: DataReaders in combination with Commands is the best performing of all the methods. B. Incorrect: DataSets require more overhead for maintaining state about changes and indexing, so from a purely performance-based standpoint, they perform more poorly. C. Incorrect: Typed DataSets require more overhead for maintaining state about changes and indexing, so from a purely performance-based standpoint, they perform more poorly. They are marginally better than untyped DataSets but still slower than DataReaders. 2. Correct Answers: B, C, and D A. Incorrect: You should never change the generated code in a Typed DataSet. B. Correct: You can write custom code in the partial class to add business logic. C. Correct: The DataSet schema is good for data validation. D. Correct: Additional business logic can be added to event handlers for DataSets to ensure that all code paths lead to the business logic being tested. 3. Correct Answer: C A. Incorrect: DataReaders in combination with Commands is the most labor intensive; therefore, you should be using Typed DataSets to prototype a project. B. Incorrect: No, Typed DataSets will allow you to prototype your project the quickest. C. Correct: Typed DataSets are the quickest at developing data access and therefore should be used for prototyping.

If the Windows Vista installation media has become damaged and you want to upgrade from one version of Windows Vista to another, it is still possible to use the Windows Anytime Upgrade media to perform an upgrade. If you do not have access to the Internet, it is possible to upgrade to another edition of Windows Vista only if you perform an in-place upgrade or if you have the Windows Anytime Upgrade media. You can only perform an upgrade from within Windows. You will not have the option of upgrading if you boot off the installation media. If you are configuring a computer to dual boot with Windows XP, ensure that you install Windows Vista after you install Windows XP. If you reinstall Windows XP after you have installed Windows Vista, it will cause problems with the boot menu. You can resolve this problem by running Startup Repair off the installation media. It is also possible to resolve this problem using the bcdedit.exe application, although this involves complex operations from the command line.

Because of these links, all computer and user objects throughout the domain receive the settings in the Default Domain Policy GPO. Although it is not recommended that you do so, you could edit the Default Domain Policy GPO and add your own settings; they would then be disseminated throughout the domain in the same way. The objects in the Domain Controllers OU, however, receive the settings from both the Default Domain Policy GPO and the Default Domain Controllers Policy GPO. AD DS combines GPO settings in this way throughout the domain. You can link multiple GPOs to a single container or link them to containers at different levels in the AD DS hierarchy, and the objects in those containers will always receive the combined settings from all of the GPOs applicable to them.

Each ISA Server role has a specific list of ISA Server tasks associated with it. Table 3-5 lists some ISA Server administrative tasks, as well as the roles in which they are performed.
