When you use a multiple-homed Windows XP-based computer with the Personal Firewall feature enabled, remote users may not be able to connect to the computer in response to a Remote Assistance request.
Also, if you are using a Windows XP-based computer with one network adapter and a modem with the Personal Firewall feature enabled, Remote Assistance does not open the firewall port on the modem connection.
This problem occurs because Remote Assistance opens the firewall port only on the first bound network adapter of the multiple-homed computer.
