I installed Windows Live OneCare and can no longer connect to my workplace via VPN. What's wrong?

A. Windows Live OneCare replaces the existing built-in firewall and although applications are enabled by default for communication, certain required ports aren't. Thus, when you attempt to create a VPN connection to a network, the process will appear to hang, then fail, at the username and password authentication stage. To resolve the problem, perform these steps:

  1. Start the Windows Live OneCare console (right-click the OneCare taskbar icon, which is normally a green circle with 1 in it, and select "Open Windows Live OneCare").
  2. On the left side of the OneCare dialog box under Other Tasks, click the "View or change settings" link.
  3. On the "Windows Live OneCare Settings" dialog box, select the Firewall tab.
  4. Click the "Advanced settings" button.
  5. Select the "Ports and Protocols" tab on the "Advanced settings" dialog box.
  6. Select the "VPN - General Routing Encapsulation (GRE)" check box, as the figureshows.
  7. Click OK to all open dialog boxes.
