This is an issue with the configuration of HOSTS file.

Check the following and retry : 

1) Make sure the port you entered is not associated with any other programs. You can try with static ports.ini.  More about Auto Configuring

2) Check the HOSTS file under C:\windows\system32\drivers\etc\hosts

•            The hosts file showld not have any extension like .txt
•    Make sure the ip address is not starting with #. # means the line is a comment
•    Check whether your system is a work-group or in a domain. Most of the system will be in a work-group, if it's domain add domain name accordingly.
•    There should be only one IP address associated with a hostname

 

      Wrong 1: 

           10.10.10.10 localhost
          172.16.136.20 prakash-pc

        Wrong 2: 

            10.10.10.10 localhost prakash-pc
   172.16.136.20  localhost prakash-pc

       Wrong 3: 

      10.10.10.10  prakash-pc
   172.16.136.20 prakash-pc
   10.10.10.10 localhost
   172.16.136.20  localhost

        Correct: 

           10.10.10.10 prakash-pc
  172.16.136.20 prakash-pc
