SYMPTOMS
After you install Microsoft Windows Live OneCare, the Cisco virtual private network (VPN) client software cannot establish a connection with the VPN server.



CAUSE
To establish a connection, the Cisco VPN client software must have some specific ports open. By default, the Windows OneCare Firewall does not open these ports. Therefore, the Cisco VPN client software cannot successfully establish a VPN connection.



RESOLUTION
To resolve this issue, use the firewall connection tool to allow the Cisco Virtual Private Network (VPN) ports to communicate through the Windows Live OneCare firewall. To do this, follow these steps:
 * 1) Start Windows Live OneCare.
 * 2) In the left pane, click View or change settings.
 * 3) On the Firewall tab, and then click Firewall Connection Tool.
 * 4) Click to select the VPN – Connect to another computer over a virtual private network.
 * 5) Click OK and close the View or Change Settings options.
 * 6) Restart the computer and test the VPN application and verify that you can establish a connection.

Restart the Cisco VPN service. To do this, follow these steps:
 * 1) Click Start, click Run, type Services.msc, and then click OK.
 * 2) In the right pane, right-click Cisco Systems, Inc. VPN Service, and then click Restart.

Try to connect by using the Cisco VPN client software. If the software still cannot establish a connection, download and install the latest update to the Cisco VPN client software.

Note When you have multiple computers that use Internet Connection Sharing, you may have to repeat these steps on each computer in the network. This includes the Internet Connection Sharing host computer.
