Windows 2000/XP: Fire up a Command Prompt (Start Menu>Accessories) and execute the command
ipconfig -flushdns
if you get 'could not flush dns' or message saying dns resolver cache could not be flushed.
If it is XP SP2 then go to Start > Run > CMD > type netsh winsock reset > enter, restart as prompted, if still no connection then go to Start, Control Panel (Network and Internet Connections then Network Connections -or- straight to Network Connections, double click on the Local Area Connection in use (usually the one that says Connected) and pick Support. Try the Repair button after Winsock fix. Use that winsock fix only if you are using SP2.
Go to "start, control panel, administration tools,services,then look for DNS Client, and make sure it's started, and set to manual.作者: digitalsony 時間: 2010-2-28 01:53 PM
