If you are receiving E02009 we have found that flushing your DNS (Domain Name System) helps to resolve this issue. At this time I would like for you to try clearing your DNS cache. To do so, please try the steps below:
- While on the desktop, press Windows Key + X.
- Select Command Prompt (Run as Administrator).
- Type ipconfig /flushdns and press Enter.
Windows Vista/ Windows 7
Windows Vista requires that you run the command prompt in Administrator Mode to perform these functions. To start the command prompt in administrator mode:
- Click Start.
- Select Programs.
- Select Accessories and locate the Command Prompt shortcut.
- Right click the Command Prompt shortcut and select Run as Administrator from the drop down menu.
- Continue with the Windows XP directions (step 2) below.
- Click Start, then select Run and type CMD in the Run box. A command prompt window should open on screen.
- Type ipconfig /release in the command prompt.
- Wait a few seconds for a reply that the IP address has been released.
- Type ipconfig /renew in the command prompt.
- Wait a few seconds for a reply that the IP address has been re-established.
- Type ipconfig /flushdns in the command prompt.
- Close the command prompt and attempt to make a connection.
This should clear your DNS cache. You may need to perform this command a few times.
If the issue persists your ISP may be providing old DNS information. Some ISPs take longer to update this information. You could also try using a 3rd party DNS service like those available at http://code.google.com/speed/public-dns/ or http://www.opendns.com/start/ . NCSOFT does not support these services, but there is information on configuring them at those sites.
