The Begin<methodName> and End<methodName> methods are used to start and complete an asynchronous invocation. By default, Web methods can be invoked asynchronously by using the CompletedEventHandler. The CancelAsync method of a Web service can be used to cancel an asynchro nous call. Polling can be performed by either using an IAsyncResult object and waiting for its IsCompleted property to turn true, or via a callback method that notifies the cli ent when it has completed. The OneWay attribute can be used to provide true fire and forget functionality. Care must be taken with the OneWay attribute because the method will not be able to retrieve any return values. Therefore, serious problems can be masked using the attribute.

The key HKLM\SOFTWARE\Microsoft\Active Setup\Installed Components contains other components with StubPath values that I haven't mentioned yet. You can prevent Windows XP from configuring any of the components when the operating system creates a user profile by removing or hiding the StubPath value in the corresponding subkey. Table 15 1 lists all the components I've already described plus the ones that I haven't. Table 15 1: Components in Installed Components Component Subkey Address Book 6 {7790769C 0471 11d2 AF11 00C04FA35D02} Internet {89820200 ECBD 11cf Explorer 6 8B85 00AA005B4383} Internet {ACC563BC 4266 43f0 Explorer Access B6ED 9D38C4202C7E} Microsoft {44BBA840 CC51 11CF Outlook AAFA 00AA00B6015C} Express 6 Microsoft {22d6f312 b0f6 11d0 Windows Media 94ab 0080c74c7e95} Player 6.4 Microsoft {6BF52A52 394A 11d3 Windows Media B153 00C04F79FAA6} Player 8 NetMeeting 3.01 {44BBA842 CC51 11CF AAFA 00AA00B6015B} StubPath "%ProgramFiles%\Outlook Express\setup50.exe" /APP:WAB /CALLER:WINNT /user /install %SystemRoot%\system32\ie4uinit.exe rundll32 iesetup.dll,IEAccessUserInst "%ProgramFiles%\Outlook Express\setup50.exe" /APP:OE /CALLER:WINNT /user /install rundll32.exe advpack.dll,LaunchINFSection C:\WINDOWS\INF \mplayer2.inf,PerUserStub.NT rundll32.exe advpack.dll,LaunchINFSection C:\WINDOWS\INF \wmp.inf,PerUserStub rundll32.exe advpack.dll,LaunchINFSection C:\WINDOWS\INF \msnetmtg.inf,NetMtg.Install.PerUser.NT %SystemRoot%\system32\regsvr32.exe /s /n /i: /UserInstall %SystemRoot%\system32 \themeui.dll regsvr32.exe /s /n /i:U shell32.dll rundll32.exe advpack.dll,LaunchINFSection C:\WINDOWS\INF \msmsgs.inf,BLC.Install.PerUser Keep in mind that even if you prevent Windows XP from configuring every component I show in the table, you might still have unwanted icons. These icons come from the Default User and All User profile folders. Remove the shortcuts that you don't want from any default user profile you've deployed. Remove the shortcuts you don't want from the All Users folder on your disk images. Caution 301

You can use the following questions to test your knowledge of the information in Les son 2, Polling Web Methods for Completion. The questions are also available on the companion CD if you prefer to review them in electronic form.

Should extensions be blocked or allowed in certificate requests Extensions can be used to restrict certificate issuance If they are used, they will be ignored by Windows Server 2003 unless configuration changes are made Extensions provide a valuable way of tightening controls on certificate issuance The decision to use them might depend on interoperability issues Are e-mail addresses required in certificates If so, e-mail addresses can automatically be added to certificates produced by enterprise CAs based on infor mation in Active Directory However, stand-alone CAs must be configured to add e-mail addresses to certificates This issue might be one more factor that pushes a design to an Active Directory integrated model, or it might simply be another con sideration in the design of the stand-alone CA.

Answers to these questions and explanations of why each answer choice is right or wrong are located in the Answers section at the end of the book.

What should be the validity period of issued certificates The validity period is the period of time from the certificate becoming valid until it expires An enterprise CA certificate validity period can be configured via settings on certifi cate templates However, the certificate validity periods of stand-alone CAs must be adjusted via changes to the registry Which types of end-use certificates can be issued by the CA and to whom The type of end-use certificate to be issued by a CA often plays a roll in the design of the CA hierarchy, but these questions are part of the certificate request process Should certificate issuance be automatically or manually approved An enterprise CA, by default, is configured to automatically issue a requested certifi cate if all constraints are met.
