Hi Keith
Open Internet Information Services from Administration tools in control panel.
Expand the tree and locate the name of the virtual directory
You may have named it Client-Server Processing according to the chapter.
Right-Click on the virtual directory and select Properties.
Go to the Directory Security tab, and press the Edit button for the Authentication control.
Uncheck Anonymous and check Windows Authentication.
thats it.
Your project should now be ok and debuggable.
(This is the usual step, it may differ depending on other settings and configuration)
I hope this helps.
