In the previous section, we compiled and installed a COM+ application that contained our example component. We used .NET attributes to specify the COM+ security settings, but we need to complete the component configuration before the component can be used. In this section, we demonstrate how to assign roles to Windows user accounts and then continue to demonstrate how the COM+ administration tool can be used as an alternative to .NET attributes or as a means to alter the security configuration specified using attributes.
The collection of COM+ applications installed on a computer is called the COM+ Catalogue. The catalogue is administered with the Component Services tool, which is included in the Administrative Tools section of the Windows Control Panels. Figure 19-5 shows the Component Services tool as it appears when first started.

Expand the Component Services tree and drill down to the COM+ catalogue for the local computer; Figure 19-6 shows the list of COM+ services for a standalone computer. The list of applications includes our example application (called SecurityProTracker, named after the assembly we created) as well as system applications that operate as part of Windows.
