In a default installation, Microsoft Terminal Services is given priority over the Microsoft Windows Network because Microsoft Terminal Services, when used, is intended to be used in place of other connections. Also by default, a connection to a Web Client Network is attempted only when the first two providers fail to respond. The Provider Order tab also displays the order for print providers. According to default settings, LanMan Print Services (the print provider used in typical Windows networks) is given priority over HTTP Print Services.

You can apply a UNIQUE constraint to a column to ensure that entering duplicate values is impossible. UNIQUE constraints, like PRIMARY KEY constraints, can be applied to multiple columns, such as in the FirstName and LastName example discussed earlier. The primary difference between the two is that you can configure multiple UNIQUE constraints to a table, whereas you can configure only a single PRIMARY KEY constraint for a table. UNIQUE constraints also allow users to enter a single NULL value. UNIQUE constraints can be referenced by FOREIGN KEY constraints. You cannot apply a UNIQUE constraint to a column when existing duplicate values are in the target column. To create a UNIQUE constraint on a column in an existing table, perform the following steps: 1. Open SSMS, and connect to the database instance that hosts the table that has the column to which you want to apply the UNIQUE constraint.

System State The collection of critical system files, such as the registry, COM+ regis tration database, and startup files that must be backed up regularly to provide for system recoverability. SYSVOL The folder on a domain controller that contains group policies and logon scripts. SYSVOL is replicated between domain controllers by the file replication service (FRS).

Learn the differences between standalone and enterprise CAs well. These topics are an important part of the AD CS coverage in the exam.

Windows XP creates and stores a list of user profiles. Table 10 1 shows the locations of user profiles depending on the scenario. The key HKLM\SOFTWARE\Microsoft\Windows NT \CurrentVersion\ProfileList corresponds to the list you see in the User Profiles dialog box. To open the User Profiles dialog box, click Start, Control Panel, Performance And Maintenance, and System. In the System Properties dialog box, on the Advanced tab, click Settings in the User Profiles area. Each subkey is a user profile, and the subkey's name is the SID of the account that owns the profile. Each profile in ProfileList contains the REG_SZ value ProfileImagePath that points to a user profile folder in %SYSTEMROOT% \Documents and Settings. Figure 10 1 illustrates the relationship between the ProfileList key and the user profile folders. This relationship is the reason you shouldn't just remove a user profile from the file system. Instead, use the User Profiles dialog box to remove user profiles, which cleans the user profile out of the ProfileList key as well as off the file system.

by using the policies that come with the Office XP Resource Kit. The kit installs these policy templates in %SYSTEMROOT%\Inf, and you must load them into a GPO to use them. Be sure to enable the policy Do Not Prompt To Convert Older Databases, which prevents accidental database conversions.

By turning the gutter off, you allow the pan gesture to enter free-style mode, enabling the operating system to send pan messages for every panning gesture performed on the pannable area with no regard to vertical or horizontal panning. This can make for a good experience when moving objects such as pictures on a particular surface or when panning a map. Imagine a mapping application in which you want to provide a full 2D panning experience. The following code snippet shows how you can configure the Windows 7 Multitouch platform to allow zoom, rotate, and panning gestures vertically and horizontally with gutters turned off. This is a useful configuration for a mapping application in which you want to allow the user to pan, zoom, and rotate the point of view of the map.

Extended controls are user-created controls that extend a preexisting .NET Framework control. By extending existing controls, you can retain all of the functionality of the control but add properties, methods and, in some cases, alter the rendered appear ance of the control.

Other than these differences, using either approach is virtually indistinguishable from using Sequential layouts.
