color (black) set to a quarter opacity. I experimented with using the DropShadow effect class inside javafx.scene.effect but found it had too much of a detrimental impact on the application s frame rate, so this Rectangle is a kind of poor man s alternative. The shadow is followed by the white photo border, and this in turn is followed by the ImageView to display our photo. We make sure the image is sized to fit the proportions of Flickr s medium-size photo, and we point to the medium photo s URL from the FlickrPhoto object. Here s the clever part: we assign the thumbnail as the placeholder while we wait for the full-size image to load. This ensures we get something to display immediately, even if it s blocky. The progress bar completes the scene graph contents. It will be visible only so long as there s still some loading left to be done. That s the scene graph; now it s time to look at the event handlers.

You are currently using ISA Server 2000 and have made the decision to move up to ISA Server 2004. You currently run ISA Server 2000 on a 450 MHz processor with 512 MB RAM. You support Internet access using Web Proxy clients and you publish a secure Web site. In addition, you support site-to-site VPN connections from a branch office to the head office through RRAS. You want to migrate to ISA Server 2004.

In these practices, you will perform several exercises that will familiarize you with tools that are useful in performing post-installation troubleshooting. These include the installation of legacy hardware, examining system stability, and configuring personalized settings.

blocksMouse: true; onMousePressed: function(ev:MouseEvent) { dragOriginX=ev.x; dragOriginY=ev.y; } onMouseDragged: function(ev:MouseEvent) { n.layoutX += ev.x-dragOriginX; n.layoutY += ev.y-dragOriginY; }

To ensure the success of your ISA Server installation, you must ensure that:

Your network infrastructure will support ISA Server implementation. DNS, domain controllers, and DHCP are essential. You have the correct operating system and hardware configurations. ISA Server, Standard Edition, can be installed on Windows 2000 Server or Windows Server 2003. ISA Server, Enterprise Edition, must be installed on Windows Server 2003. Your ISA Server provides sufficient performance. A single server running ISA Server 2004 will provide enough throughput for most small to medium-sized organizations.

Practice 1: Add Legacy Hardware In this practice, you will use the Add Hardware Wizard to search for legacy hardware. A legacy device is one that will work with Windows Vista but that is not automatically detected and installed by the operating system. Legacy devices are not plug and play compatible. In this practice, you will install a legacy loopback adapter. Although they are virtual devices, you can use loopback adapters to perform network diagnostics. Performing this exercise will give you an understanding of the manual installation process. To complete this practice, perform the following steps: 1. Click Start, and then click Control Panel. 2. Ensure that Control Panel is set to Classic View. 3. Open Device Manager. 4. Right-click the Computer Name at the top of the device tree, and then click Add Legacy Hardware. 5. In the Welcome To The Add Hardware Wizard page, shown in Figure 3-16, click Next.

There are three ISA Server 2004 installation types. A typical installation installs ISA Server Services as well as ISA Server Management. The full installation installs all four components of ISA Server including the Firewall Client file share and the SMTP Message Screener. A custom installation allows you to select which components will be installed. When you install ISA Server, ensure that you configure the IP addresses for the internal network correctly. When you perform an in-place upgrade, you install ISA Server 2004 on the same computer that is running ISA Server 2000. When you migrate the ISA Server 2000 configuration to ISA Server 2004, you install ISA Server 2004, use the Migration Tool to export the ISA Server 2000 configuration, and then transfer the configuration information to ISA Server 2004. In either scenario, most configuration settings are migrated to ISA Server 2004.
