Unable to create the virtual directory.Could not find the server'...........' on the local machine

Hi all,

Unable to create the virtual directory.Could not find the server'...........' on the local machine.Creating a virtual directory only supported on the local IIS server.

This is the error exception I get from my project when i tried to change project properties>web>use local IIS web server.

This is sound silly but I have to ask for help on solving the problem.In previous I did create multiple project that uses the same name of url.now it might have duplicate entries of the url in IIS7.can i know how i can find the duplicate url and remove them so that i can reuse the same virtual url for my project?

Thanks in advance.
