Hi Charlie,

>That's where I get confused. What is the difference between setting application protection on virtual directory and putting DLL in a COM+ package? They both allow you to "unload" application without stopping web server. Do they both offer JIT?

When you enable application protection, this basically means that IIS 5 creates your COM object in a separate EXE (DLLHOST.EXE). This is the same EXE that is used in COM+ Services (MTX.EXE was what MTS used). In fact, internally IIS creates a COM+ application for each virtual directory and adds a component for each directory with most COM+ features disabled.
