Localhost not found (404) iis

asp.netiislocalhostvisual studio 2012

I am having several issues with the DNS localhost on my computer.

Some instruction is redirecting all my explorers, including visual studio somewhere else than 127.0.0.1 when I visual studio or any browser looks for localhost.

Where can such thing be happening? I recently changed my hosts file to point localhost somewhere else, but then it did not work so I switched it back, so that cant be the problem.

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
127.0.0.1 localhost
::1 localhost

I have also unistalled and installed IIS, so is not a problem of iis not redirecting properly..

I am not being able to run Visual Studio solutions because of this problem.

I have tried pining 127.0.0.1 and it responds, I have also tried localhost and it also works, but when I type localhost on a browser it redirects to a "404" page.

Make sure that IIS is actually configured to listen on 127.0.0.1 (perhaps you removed the binding previously?)

netsh http show iplisten IP addresses present in the IP listen list: 127.0.0.1

You can add additional IPs like so:

netsh http add iplisten ipaddress=10.0.0.10

Asp.net-mvc – ASP MVC in IIS 7 results in: HTTP Error 403.14 – Forbidden

Maybe it's useful to someone: After converting my app to MVC 4 with .NET framework 4.5 and installing the framework on my server with IIS 7.0 I encountered the same 'forbidden' error mentioned in the question. I tried all options described above to no avail, when I noticed the

<system.webServer>
 <modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>

was missing from my web.config. After adding this, everything worked. Simple, but easy to overlook...

EDIT:

Of course the solution above will work, but it is indeed a waste of resources. I think it is better to add the routing module as pointed out by Chris Herring in the comments.

<system.webServer>
  <modules>
    <remove name="UrlRoutingModule-4.0" />
    <add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />
  </modules>
</system.webServer>

Using Custom Domains With IIS Express

This is what worked for me (Updated for VS 2013, see revision history for 2010, for VS 2015 see this: https://stackoverflow.com/a/32744234/218971):

Right-click your Web Application Project ▶ Properties ▶ Web, then configure the Servers section as follows:
- Select IIS Express ▼ from the drop down
- Project Url: http://localhost
- Override application root URL: http://dev.example.com
- Click Create Virtual Directory (if you get an error here you may need to disable IIS 5/6/7/8, change IIS's Default Site to anything but port :80, make sure Skype isn't using port 80, etc.)
Optionally: Set the Start URL to http://dev.example.com

Open %USERPROFILE%\My Documents\IISExpress\config\applicationhost.config (Windows XP, Vista, and 7) and edit the site definition in the <sites> config block to be along the lines of the following:

<site name="DevExample" id="997005936">
    <application path="/" applicationPool="Clr2IntegratedAppPool">
        <virtualDirectory
            path="/"
            physicalPath="C:\path\to\application\root" />
    </application>
    <bindings>
        <binding
            protocol="http"
            bindingInformation=":80:dev.example.com" />
    </bindings>
    <applicationDefaults applicationPool="Clr2IntegratedAppPool" />
</site>

If running MVC: make sure the applicationPool is set to one of the "Integrated" options (like "Clr2IntegratedAppPool").
Open your hosts file and add the line 127.0.0.1 dev.example.com.
► Start your application!

Some great advice from the comments:

You may need to run Visual Studio as Administrator.

If you want to make other devs see your IIS run netsh http add urlacl url=http://dev.example.com:80/ user=everyone

If you want the site to resolve for all hosts set bindingInformation="*:80:". Use any port you want, 80 is just convenient. To resolve all hosts you'll need to run Visual Studio as an administrator
