Http.Sys Config Tool

I want to test some demo XData Project, however it gets the following error during ordinary launch (http, port 2001):

Error says that "A file cannot be created when it already exists" and hints me to reserve the URL in Http.Sys Config Tool. And when I try to do it, it says the same, although I cannot find anything using netsh command (I'm using Windows):


That http://127.0.0.1:2001/ratioserver/ entry was the only thing related, which I could add, but it seem to have no effect on URL reservation attempts.

Is there anything I do or understand wrong in this issue? And how possibly I can fix it?

The error indicates that you already have a server running at that address, and you trying to launch yet another one at the same address, which is not allowed.
