The third gesture that is commonly used in multitouch applications is rotation. This is a dualtouch gesture where the user places two fingers on the screen and moves them in a radial motion relative to each other. WPF can capture this and raise an event that can be used to transform the rectangle and provide rotation. Because you ve been building the event handler for the manipulation up to this point, you can just continue to add on to what you have. So if you ve just jumped into this section, it s advisable to go back and read the previous two sections where we first added translation gestures and then added scaling gestures. The rotation code will build on top of the code for these gestures. You perform a rotation around a certain point. In this case, it makes sense to perform it around the center of the rectangle. You already have the Point object that represents this, so you can simply rotate around that. Additionally, the Manipulation object that the function has been using provides feedback on how the user has applied a rotate gesture with his fingers, so all you need to do to add rotation to this application is take this rotation and apply it to your matrix around the desired center point. You can do this with the following code:

Every member computer in an Active Directory domain maintains a computer account with a user name (sAMAccountName) and password, just like a user account does. The computer stores its password in the form of a local security authority (LSA) secret and changes its password with the domain every 30 days or so. The Netlogon service uses the credentials to log on to the domain, which establishes the secure channel with a domain controller.

Later, you will design your DNS infrastructure based on the topology of your network. For now, you should be able to look at the current system and determine how it is configured.

4. If this is the first time you run the Backup Once Wizard, choose Different Options and click Next. If not, you can also choose The Same Options. 5. Click Full Server (recommended) and click Next. Note that you can also check Custom, but you will not be able to omit anything other than specific volumes. You will not be able to omit folders. Remember that your DCs should be single-purpose servers and, as such, you would not need to exclude any volumes. However, if you are backing up to a local disk, you should exclude this volume from the backup operation. Note that when you use the custom option, you can select an option called Enable System Recovery, which will automatically capture all the data required to recover a full system.

Download WSUS from the following address: www.microsoft.com/ windowsserversystem/updateservices/downloads/WSUS.mspx. Install WSUS on a test server. Using the Default Domain Policy in the Active Directory domain you created, configure the Windows Update Administrative Template so that all computers in the domain point to the WSUS server for Windows Updates. (The WSUS server itself does not need to be in the domain.) On the SQL Server computer, run wuauclt.exe /detectnow at a command prompt to register the computer in WSUS.

Common service calls associated with newsgroups include blocking messages from a particular sender, blocking unwanted messages, and resolving problems with sending or receiving posts. Users might also need to cancel a subscription to a newsgroup or view newsgroups without subscribing at all.

recipient of messages, authenticate Web clients and servers, identify smart cards, and encrypt files. Table 1-4 lists and describes the subcomponents included in this Windows Server 2003 component.

In Lesson 1, you briefly examined the various zone types available in Windows Server 2003. Here, the zone types will be addressed in more detail so that you can determine which zone type is best suited for your organization.

Mutex class The purpose of the Mutex class is to provide a locking mechanism, and it works in much the same way as the Monitor class. The major difference is that the Mutex class can lock data across AppDomain and process boundaries. To use a Mutex, follow these steps: 1. Create an instance of the Mutex class to be shared across any threads:
