WRP protects the integrity of system files and system registry settings, including device drivers and device settings . Drivers are added to the list of WRP-protected files on the system only if they have been specifically flagged for protection by WRP when being staged to the driver store . When a driver package has been specifically flagged for WRP protection and that driver package is staged to the driver store, an event is logged to the event logs to indicate this . To verify that a third-party driver you plan to install will be protected using WRP, open the INF file for the driver and look for Pnplockdown=1 in the [Version] section . Microsoft recommends that ISVs who develop third-party drivers for Windows 7 include this setting (called the lockdown flag) in their INF files, which causes WRP to prevent users with administrative privileges from deleting or modifying the driver files referenced in the INF file . However, this is only a recommendation; ISVs are not required to include this setting in case compatibility issues should arise .

Mail-enabled contacts are a convenient way to add external correspondents to the GAL. Typically, contacts represent people working in other companies to whom a number of users need to send messages on a frequent basis. They are commonly used to facilitate contact with specific individuals or utility mailboxes for external vendors such as PR agencies. To create a new contact, under Recipient Configuration, go to the Mail Contact section and click New Mail Contact in the action pane. The wizard is very straightforward, because essentially all you re doing is creating an Active Directory object to hold some details of the contact including her email address. Creating a mail contact with EMS is more interesting because more options are exposed. Here s an example of a command that creates a new mail-enabled contact. Note that the email address must be unique.

Set up a server with the same name as the server that is recovered. Run Setup /m:RecoverServer to install the Exchange role and fetch the configuration information from Active Directory. Restore custom prompts and audio files if required. Restore GAL grammar configuration files if required.

You can use the QoS Traffic Generator to test your QoS implementation by generating different types of traffic, at varying rates, with specific characteristics . The following example demonstrates using the QoS Traffic Generator to send UDP traffic to the IP address 10 .12 .1 .1 at a rate of 5 Mbps for 5 seconds . First, start the QoS Traffic Generator in sink mode on the destination computer .

The digital signature of the component is matched to the service provider, so that clients can verify they are downloading the control from the correct service provider (and not an attacker-modified control that could do terrible things to their systems).

to dependency injection. The framework is the Managed Extensibility Framework (MEF). Dependency injection is only part of the work that MEF tries to do. In brief, MEF provides a programming model for classes to declare which properties they intend to import and which properties they intend to publicly export.
