No reply from global DNS but getting reply from loop back address-cannot go online

This post is the continuation of the post cannot go online where there is no reply from the global DNS server while ping to it. To get the continuation of the topic I recommend you to read the post given below first and come back to this post.

I cannot go online- The basic troubleshooting steps


When you are not getting reply from the global DNS server the possible reasons are:

1. The TCP suit on your computer might be corrupted

2. There is some connection issues on your network

3. There is no internet connection from your service provider.


In this post I am going tell how to check whether your TCP/IP suit on your computer is corrupted or not. To check it we need to ping the loop back address on your computer.
If you are getting reply from the loop back address it shows the TCP/IP suit is working on your computer. To perform this :

1. Click on start
2. Click on run and type cmd on it then click OK(On Vista type command on search and press enter)
3. On the command prompt type the following command

ping 127.0.0.1 now press enter

If you are getting replies then the TCP/IP suit of your computer is fine. Now the next steps you need to perform is to check whether your local network connection has any issues or not. To check it click on the link below.
