    cannot communicate with primary dns server - Vista Suspend/Sleep/Standby issue

    Since I upgraded my system to Windows Vista Home Premium (from XP), I started facing internet connections issues after waking up my system from Sleep Mode or Standby Mode. When it comes back from any of these modes, I use to get an error message saying “cannot communicate with primary dns server” but when I use to check my connection, I see my IP Address and DNS servers are proper.

    After struggling with this problem finally I found a solution which fixed the problem permanently. So If anyone of you guys facing the same problem and looking for solution, just go through the following:

    • Right click “My Computer” icon from the desktop and select Manage.
    • Click Device Manager from the left of Computer Management Window.
    • Right click your network adaptor and select properties
    • Click Power Management tab
    • Select "Allow the computer to turn off this device to save power."


    That’s it. Problem fixed.
