Re: "Internet Explorer cannot display the webpage" from IE7 - ASP.NET Development Server Error?

I'm still having the stated problem.

I goto view in browser in Visual Studio and the page errors "cannot be displayed", however; I can type in the directory and view all the files in the folder through the browser on http://LocalHost:Port/... but any file I click on regardless of extension throws the cannot be displayed.

First thing I did was check the security software... Only Windows Firewall installed and it's disabled. (tried adding exceptions anyways just in case) No Antivirus is installed as this computer strictly makes websites, no E-mail, it's isolated from the rest of the network, and I don't go to many sites beyond ones like ASP.NET, the sites I maintain, etc.

Second, after reading this I checked my HOSTS file, 127.0.0.1 Localhost was there as it should be. and I'm not using IPv6, Running XP Professional SP3 (32bit), I've tried going to the page using 127.0.0.1 to see if it was a DNS issue, same results as localhost which takes DNS out, I'm not on a proxy, so that's out, No firewall running... scratch that, and hosts is okay, and well I'm more or less out of ideas.

The ports are matching server and browser wise, and I even tried installing IIS to see if it'd pick it up. No luck there, I'm sure I could get IIS to host, but I'm only looking at using this to test and debug so I'd prefer save the headaches from running a local IIS service for a site I host else where...

Any ideas? cause I'm about out of them.

Close any sites/projects in VWD and then close VWD. Locate the 'hosts' file at C:\Windows\System32\drivers\etc\hosts

Open the Hosts file in Note Pad and check to see if the line below is there:

127.0.0.1 localhost

If it is not, add it. Save, and close the file. Next, start VWD, open a site and press Ctrl+F5. The dev server should start, and your default page should be displayed in your browser.

This solution has worked for many people. Please let us know if it works for you, or no.

Cheers,

I Had the same problem running on Vista.

My solution was removing the next line in the windows host file C:\Windows\System32\drivers\etc\hosts

::1 localhost

This is an IpV6 entry. Put a # in front of it.

Awesome! That was exactly it. This issue just appeared out of nowhere on me the other day and was making me nuts!

Get rid of the ::1 and replace it with 127.0.0.1

The line in the HOSTS file should look like this...

127.0.0.1 localhost

Worked for me... Good luck

Hi kfj,

I encountered the same problem yesterday, which I did not have when I used Visual Web Developer 2008 Express Edition last time about one month ago. Your solution worked for me.

Thanks a lot.

If editing the settings in NOD32 hasnt helped you, look at this solution which helped me......

The problem has to do with the fact that there are 2 entries for local host in the hosts file ([Windows directory]\System32\drivers\etc\hosts).

One for ipv4 and one for ipv6.However i had both the entries remarked.

Example:

127.0.0.1 localhost
::1 localhost

To solve the problem you can remark one of them. The example below remarks the ipv6 entry.

127.0.0.1 localhost
# Causes problems when using localhost ->
#::1 localhost

Note that you might not be able to modify the hosts file even if you are running as an administrator.

The following Microsoft KB explains how to change the hosts file:

http://support.microsoft.com/default.aspx?scid=kb;en-us;923947

Hope this helps...

Hi, I too have had this problem today, yesterday all was fine! I don't have NOD AV installed and IPv6 has always been enabled without issues!. According to this post - http://msmvps.com/blogs/donna/archive/2009/03/10/windows-defender-false-alarm-triggered-by-hosts-file.aspx - the issue is with a windows defender update which was deployed via automatic update on Monday.

I had the same problem. And I looked at the hosts file.

The problem is not the ::1 for IPV6, but the missing 127.0.0.1 localhost entry.

Correct hosts must look like this in Vista:

# Copyright (c) 1993-2006 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

127.0.0.1 localhost
::1             localhost

One of the updates yesterday must have deleted the first line at my system.

Thank you very much.

I had this same problem, and it has to be a security update from Microsoft that removed this, because it worked before the weekend, and now suddenly it didn't .

Adding the line
127.0.0.1 localhost
in the hosts file located in "C:\Windows\System32\drivers\etc\"
did the trick for me, and I don't have the NOD antivirus that seems to be the case for most replies in this thread.
