APPLIES TO


 * Windows Live OneCare

-



SYMPTOMS
When you use a virtual private network (VPN) program on a computer that has Microsoft Windows Live OneCare installed, you may receive an error message that resembles one of the following:

Error message 1

Remote Host Unavailable

Error message 2

Unable to establish a connection



CAUSE
This issue occurs because Windows Live OneCare blocks the protocols that are required by the VPN program to establish VPN connections.



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

Warning We recommend that you enable a protocol only if you need it. Enabling all the protocols in Windows Live OneCare can make the computer more vulnerable and less secure.
