Administering an ISP Installation

Overlapping Virtual Servers

You cannot install FrontPage Server Extensions onto a virtual server that overlaps another virtual server (nested virtual servers). If you try to install them, you’ll get the following error message:

Unable to create a web for the url "/" because its root directory, "c:\Inetpub\wwwroot\web", falls below the root of another web in the directory "c:\Inetpub\wwwroot".
