SYMPTOMS

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.

CAUSE

This problem occurs because Remote Assistance opens the firewall port only on the first bound network adapter of the multiple-homed computer.

To resolve this problem, obtain the latest service pack for Windows XP. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

WORKAROUND

To work around this problem, use any of the following methods:
  • Change the binding order of the network adapters.
  • Temporarily disable the Personal Firewall feature while you receive Remote Assistance.
  • Manually open the Remote Assistance ports.
Note that if there is only one network adapter and a modem and you change the binding order, the problem is not resolved.
