Why can't I make an http request to the ASP.NET development server on localhost?

I have an ASP.NET project (VS2008 on Windows 7 with either webforms, MVC1, or MVC2 -- all the same result for me) which is just the File->New hello world web project. It's using the default ASP.NET development server, and when I start the server with F5, the browser never connects and I get a timeout. I tried to debug this by telnetting to the development server's port while it was running, and I got the same result:

C:\Users\farmercs>telnet localhost 54752
Connecting To localhost...Could not open connection to the host, on port 54752:
Connect failed

I can see in the system tray that the server thinks it's running, and a netstat -a -n command shows that there is indeed an active TCP listener on that port.

This worked in the not-too-distant past, and I could work on web projects using the development server. One thing that has changed since then was that I installed the Microsoft Loopback Adapter to accommodate a local development Oracle installation. I'm not sure this is the problem, but it seems a likely culprit.

I also tried to hit the port using the server name itself (http://mycomputername:54752) but with the same result.

So, what could be blocking me from connect开发者_StackOverflow社区ing? And if it's the loopback, then what is a good way for me to retain my ability to connect to my development Oracle server while still being able to use the ASP.NET development server?

have you checked your host file?

%SystemRoot%\windows\system32\drivers\etc\host

look if there is any redirection of localhost or 127.0.0.1 to somewhere else rather than your pc
