If you are facing a difficult software distribution issue, and you ve verified that the software deployment options are correct, you may want to enable Application Management debugging. To do this, you must go to the system experiencing the problem and log on as an administrator. You then enable Application Manage ment debugging by editing the registry as described in the following steps: 1. Click Start, click Run, type Regedit and then press Enter. In the Registry Editor, expand the following path: HKEY_LOCAL_MACHINE\Software\Microsoft\ Windows NT\CurrentVersion. 2. Right-click the CurrentVersion key, point to New, and then click Key. Type Diagnostics as the new key name, and then press Enter. 3. Right-click the Diagnostics key, point to New, and then click DWORD Value. Type AppMgmtDebugLevel as the name of the new value, and then press Enter. Double-click the AppMgmtDebugLevel value. 4. In the Edit DWORD Value dialog box, type 4b in the Value Data box, and then click OK. Close the Registry Editor. Once you restart the computer (for applications assigned to the computer) or have logged on the user (for applications assigned or published to the user), you should be able to find the AppMgmt.log file in the %Systemroot%\debug\ usermode folder. Read the entries in this file to gain insight into the problems that are occurring with the application installation. If you don t see this log file, it could be that the application deployment policy is not even reaching the local cli ent system. This could be the case if the policy is disabled or possibly being fil tered through inheritance blocking or security filtering. After you complete your debugging, be sure to remove the AppMgmtDebugLevel key so that you don t waste system resources logging information that you don t require.

This capability, shown in Figure 1-5, was introduced in the original release of Windows XP and significantly overhauled in SP1. In SP2, the default settings automatically download and install updates without requiring your intervention. Some of the most insidious security breaches occur on the Web, where unscrupulous page designers try to entice an unsophisticated user into installing a hostile ActiveX control or program. New security features in Internet Explorer block unwanted pop-up windows, prevent downloads of potentially dangerous programs, and give you greater control over browser add-ons, as shown in Figure 1-6. Secure high-speed networks based on wireless technology were an expensive novelty when Windows XP was introduced. Today, wireless networks are inexpensive and extraordinarily popular. Service Pack 2 adds a new Wireless Network Setup Wizard to Windows XP and makes it much easier to secure that network from intruders. Figure 1-7 shows the revamped dialog box that you can use to connect to a wireless network.
