I seem to have lost all network connectivity after installing MSN Monitor Pro and WinPCap 4.1 beta 3. It _may_ be unrelated but everything was working fine before I did this.

After I installed it and tested it everything still seemed to be working ok. After a reboot however I seem to have lost connectivity. I have now uninstalled both apps but not managed to regain network connectivity. Although the System Tray Icon tells me I am connected at 100MB (I have a broadband router connected via a hub) when I try and report my network status with ipconfig /all I get nothing more than the simple " Windows IP Configuration " response.. no details whatsoever.

Likewise with Control Panel Network Connections Local Area Connection -Support - Details - there is absolutley no data, no details, just blank!

Have I broken something?

What should I look for ?

Log on as an administrator, go Start > Run and type: "cmd". In the window that appears type: "netsh winsock reset". When the program is finished, you will receive the message: "Successfully reset the Winsock Catalog. You must restart the machine in order to complete the reset." Close the command box and reboot your computer.

Go Start > Run > type: "cmd" In the window that appears type: "ipconfig /flushdns". Close the command box.

Go Start > Control Panel > Network Connections. Right click on your default connection, usually Local Area Connection or Dial-up Connection if you are using Dial-up, and and choose Properties. Double-click on the Internet Protocol (TCP/IP) item. Select the radio button that says "Obtain DNS servers automatically". Reboot.

Warning: Some Internet Service Providers need specific DNS settings. You need to make sure that you know if such DNS settings are required before you make this change.
