    Have windows 7 os and have a problem connecting to certain websites e.g. google, hotmail etc but otherwise can surf the net. Tried diagnosing problem and the message came up "your dns server might be unavailable." I have tried troubleshooting from online advice - resetting the router, restarting everything, tried resetting the dns cache and changing the ip address but that just lead to an ip conflict. Any advice would be appreciated.

    this maybe a malware issue or maybe a DNS issue
    but first check hosts file - see below

    next try google open dns

    Checking the Host file

    • Open Notepad - Start> Programs> Accessories> and right click on Notepad select "Run as Administrator" to open a notepad
    • Now goto 'File' > 'Open' and browse to the HOSTS file - which will be located in C:\WINDOWS\system32\drivers\etc. - you may need to change the drop down box next to the file name:box from Text Documents (*.txt) to ALL Files (*.*)
    • The file should look like the info at the bottom of this post

      Now all you need to do is copy and paste those results into a reply here
      to do that:
      From the notepad menu - choose Edit - Select all
      all the text will now be highlighted
      Next
      From the notepad menu - choose Edit - Copy

      Now go back to the forum - goto the reply and then right click in the reply box and paste the results.
      The results from the notepad should now appear in the forum reply.

    • Once you are finished, go up to 'File' and click 'Save'. Make sure to change the Save as Type: box to All files.
      Otherwise, Notepad may add a .txt extension to the file which will keep it from working. If you don't have your system set to show extensions, it's easy to miss that.

    Google public DNS
    Note using google public DNS servers from outside the US may actually slow performace - so use the following as a test to identify DNS issues - if these resolve the issues , then we need to investigate further to optimise the use of DNS


    Google public DNS
    http://code.google.com/speed/public-dns/

    Theres also a link on how to setup those DNS IP address up on a PC
    http://code.google.com/speed/public-dns/docs/using.html

    How to set XP here
    http://techie-buzz.com/how-to/google-public-dns-on-win7-and-winxp.html

    Then once you have set up those DNS entries

    Flush & register DNS

    Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):
    In the command prompt window that opens, type the following commands:

    Ipconfig/flushdns
    ipconfig/registerdns


    If you receive the message
    The requested operation requires elevation.
    Then please open the command prompt as administrator
    Start> All Programs> Accessories and then right click on Command Prompt, select "Run as Administrator" to open a command prompt.

    now type the command again

    Hi,

    Please have the IP address and DNS server address set to "Obtain Automatically"
    Then reply back with ipconfig result from the command prompt.
