	How Does MTS Fit into the IIS/Web Application Model?

	IIS applications (and by that I mean applications as defined in the Internet Service Manager applet) all run inside MTS. Even the root Web runs in an MTS package. A package consists of one or more components grouped under a package name—in other words, a collection of components. You can use the Microsoft Transaction Server Explorer, which runs as a snap-in to the Microsoft Management Console (MMC) to view the packages and components installed on your system.

	Using Microsoft Transaction Server Explorer

	To launch the Transaction Explorer, click the Start button and select Programs Windows NT 4.0 Option Pack Microsoft Transaction Server Transaction Server Explorer (see Figure 12.1). If you're running Windows 2000, the COM+ Explorer provides essentially the same services.

	The Transaction Explorer shows you the list of packages installed on your computer. Click the plus signs until you see the Packages Installed entry (see Figure 12.2).

	Figure 12.2: Microsoft Transaction Explorer—Packages Installed

	You'll notice that several of the entries begin with IIS. Each entry is a separate application. The name of the IIS root application is IIS In-Process Applications. Components that run in the IIS process space appear here. Click the plus sign to expand the IIS In-Process Applications entry, then double-click the Components item to view the components in the right-hand pane (see Figure 12.3).

	You can change the view in the right-hand pane to a list, which helps when the components have long titles. To show the list, click the View button on the toolbar and select List View (see Figure 12.4).

	You can explore the other packages the same way.

	Warning		Look, but don't touch! Don't change any of the settings for the IIS packages. Changing the settings can cause the applications or even IIS to fail.

	You should spend some time becoming familiar with the various settings and dialogs in MTS. I'm not going to provide details about them in this book other than those necessary to show you how to run components with WebClasses.
