Reply from 192.168.0.3: Destination host unreachable
I am running a ASP.net website on Windows 8.1 with IIS. I could access my website all morning. I did not make any changes. By afternoon I could not access my website. If I ping my IP address or my website I get: Reply from 192.168.0.3: Destination host unreachable. I am new to networking. Can anyone give me any help in resolving this problem?

192.168.0.3 is your IP address. first try run->> cmd--> enter..> type:   ipconfig /flushdns -->enter (it's reconfiguring your dns to recognize all known ip address) ping again. If not helped then write your website address to lmhosts list.

Running ipconfig /flushdns did not help. I still cannot ping my website or IP address. I get: Reply from 192.168.0.3: Destination host unreachable. Please, what do you mean by write your website to lmhosts list?

Ok lets figure this issue of yours out. 

First, please post the ipconfig result,

then, try to ping 127.0.0.1 from your webserver and see what you get...

Goro windows-->> system32-->> Drivers-->> etc folder

open file hosts with notepad and at the end of file write 

192.168.1.2 (your web server ip address) google.com (your webaddress name)

save it. But when before saving be sure that you have write access to this file or you have administrator privileges to make changes in file.

Later when you will ping your address you can resolve the ip or you can open your web address through IE

Hi Lori,

>>I am still getting: Reply from 192.168.0.3: Destination host unreachable when I ping my website and IP address.

>>The IP address of my webserver is 192.168.0.12.

According to the ipconfig information , it seems that hyper-v is not enabled on win8.1 .

I need to confirm that there are two computers , one is your 8.1 computer with IP 192.168.0.3 , the other is web server with IP 192.168.0.12 .

If web server is a physical computer please ensure that it is connecting to same LAN with win8.1 computer , in other words they should be able to ping the gateway 192.168.0.1 .

In addition , please disable firewall on each computer for troubleshooting.

Hope it is helpful to you .

Elton Ji

I am on one machine on a wireless network. It seems my IP address is changing. Because I used to have it as 192.168.0.12. But now ipconfig is showing 192.168.0.3. Can an IP address change? If so how do I make it static? I logon to my IIS machine locally.

June 30th, 2015 4:12pm

If you configured IP address to automatic then it will take IP address from DHCP. If you want to make it static then go to network adapter properties as I explained before on changing DNS address, it's the same thing, same way. Just goto control panel on the left side of the panel you will see the 'change adapter settings' link. Click on it and new windows will open. From the list find the wireless adapter (if you connecter with wireless) or Local area connection (if you connected with Cable also you need to see the 'connected' below the connection maybe you will have few local area connection but only one of them will show the conencted) 

Follow the step: 

save and wait 1 minute and check!

Hi,

Why does my ip address show up as 192.168.0.12 when I ping my website name? When ipconfig shows my IP address as 192.168.0.3. Here is a paste of my pinging my website name:

Your IP is not 192.168.0.12 it's 192.168.0.3

The 192.168.0.12 is the your web server machine ip address. Reply from is your IP address. Because when you pinging any web address or machine then first routing is going through your DNS addresses. If there is routing to the destination then you will have response from web address about ping TTL and packet size. But in this situation your computer didn't find any record for that adress and cannot reach to that address your machine is responced to you that Destination host is unreachable.

I'm sorry, I don't know what you mean by Hyper-V machine. I am running one windows 8.1 machine with IIS running on it. I am on a wireless network. I was running a ASP.net website okay when all of the sudden without any changes I could no longer access my website. I then started to get the destination host unreachable error. Should my IP address I have configured with IPage, my domain name host, point to my router IP or my machine IP?

Does it virtual machine running in your computer or it's a normal physical computer running in another place, or it's virtual machine running in another physical machine?

Hi Sir,

The possible fix for the ICMP error message "Destination Host Unreachable" :

Make sure that local host is configured correctly

Make sure Destination Computer/Device is up

Disable the Firewall and check for the issue

Perform a tracert to the destination IP and check where the problem lies

My website server is Internet Information Services running on a Windows 8.1 machine which has an IP address of 192.168.0.3. I don't have a webserver running on 192.168.0.12. I don't know where that number is coming from in the above listed ping I copied and pasted. Here is a tracert of my IP address:

C:\Users\Lori>tracert 192.168.0.3

Please, how do I make sure my local host is configured correctly and how do I disable the firewall? Can someone also tell me if the configuration I have with IPage where my domain name is registered should point to my router IP address or my machine address which is running the website?

From your post showing the output from ipconfig, it shows that you are receiving your IP address from DHCP and that DHCP is running on your wireless router.  DHCP is a protocol to automatically hand out IP addresses and configurations so you do not have to do it each time you want to use the computer.  This is how you can use wireless in any coffee shop, wifi hotspot, etc.

But, it also means that you are not guaranteed to have the same IP address each time you use your computer.  It looks like you may have initially had an IP address of 192.168.0.12 when you set up IIS.  But then for whatever reason (many to consider), the address on your wifi changed to 192.168.0.3.

If your IIS is running on your local computer, put http://localhost into your browser and it should bring things up.  If your system is getting its IP from DHCP, you cannot rely on a specific address for your IIS.

When I put http://localhost into my browser I get:

What is the URL that you used initially to gain access to your web server?  If your web server is running on the machine from which you are trying to access it, then localhost should work when you substitute for the IP address.  At a minimum you should be getting an IIS splash page (I just installed IIS on a Windows 8 system to see what would happen), not a 404 error.

Example.  Originally it worked with http://192.168.0.12/somesite.  Replace to be http://localhost/somesite.  Or http://127.0.0.1/somesite.

We must be missing something.  From a PowerShell window type the command Get-Process.  It should show an alphabetical list of processes running on your system.  One of those should be w3wp if you are running IIS on your system.  If that isn't there, we need to look farther.

If you do not see the w3wp from the previous step, take a directory of C:\.  You should find a directory named inetpub.  If that's missing, then you do not have IIS installed on the system you are running from and we will really need to understand your configuration.

July 8th, 2015 3:01pm

I was using www.lorihalderson.com from two different machines to access my webpage until all of the sudden it stopped working, I didn't make any changes. I think that my IP address changed.

I get a splash page when I go into IIS Manager and turn the default website to running when I enter http://localhost in a web browser. I had turned that website off.

When I put in http://localhost/www.lorihalderson.com or http://127.0.0.1/www.lorihalderson.com I get a 404 error.

When I do a Get-Process from a PowerShell window I do not see w3wp. I do however have a c:\inetpub directory.

OK. Using www.lorihalderson.com very definitely depends upon DNS name resolution.  The key is finding out where www.lorihalderson.com is defined.  That is not a typical entry you would have for accessing a web site running locally on your machine. 

I understand this is new to you, and my instructions were not clear enough.  But http://localhost/www.lorihalderson.com will create an invalid entry.  What I meant was for you to replace whatever you had initially used to access your web site with the localhost or 127.0.0.1.  Both of those are reserved for accessing the local machine via the network.  So if you had previously been accessing your system by http://www.lorihalderson.com and that had pointed to your local machine, replacing it with http://localhost should have brought things up.

Again, it comes back to where it is trying to resolve the name.

In your post where you showed us the ipconfig output, it shows that you are connected to a Dell wireless router.  It is also saying that the wireless router is the DNS server.  That is a little uncommon.  Generally the wireless routers do not serve as DNS servers, though they often serve as DHCP servers.  So from what I see, I am doubting that you have DNS configured correctly.

Let's try something else for now.  If you are not seeing w3wp running as a process, then IIS is not running on your system.  Maybe you did it too soon after the system rebooted.  But if you go to the default web site and then look for the process, it should be there.  Otherwise you would not be able to get to the default web site.

Here is a picture of my default web site configuration in IIS Manager.  As you can see in the lower right, it actually gives you the ability to browse to any web site you have.  In my case, I can select only the default, but if you have more than just the default, you can select the other web site and used the Browse Website to get to the selected site.  See if you can get to it that.  Then tell us what you see instead of the 'Browse*:80 (http)' that you see in my screen.

July 8th, 2015 5:44pm

When I am in IIS Manager on the right hand side it says Browse www.lorihalderson.com on 192.168.0.3:80 and when I click on it I get: This page can't be displayed error message.

When I click on the default web site in IIS Manager I get the IIS splash page. On the right hand side it shows Browse *:80(http) for the default web site.

When I put in http://localhost or http://127.0.0.1 I get the IIS splash page.

Based on this, I agree with Tim that this is a DNS related issue. I have seen wireless routers act as DNS servers before (the Netgear router provided by my ISP has this functionality, though I promptly disabled it for my local MS DNS, but that is for another post), but this is unusual. So on a lark, I attempted to ping www.lorihalderson.com from my workstation and it resolved to 192.168.0.3. My ping failed because that IP address is for private use and cannot be contacted across the open internet. 

This means that who ever you registered lorihalderson.com with (GoDaddy, Network Solutions, etc.) is hosting the DNS and has that record. This would be bad practice for a production website. My suggestion would be to abandon the use of the name and use the 192.168.0.3 address to contact the site locally or remove the www record pointing to 192.168.0.3 (a good idea regardless) and edit the host file as suggested previously.

To do this, start Notepad as an administrator, open the hosts file shown above and add the last line. The run ipconfig /flushdns.

I realize this is a lot to take in if you are new to networking, but it is a great way to learn.
