On a Windows XP-based computer, you execute a Remote Assistance invitation file to connect to a novice’s computer. However, the Remote Assistance session fails. Also, you receive the following error message:
This problem occurs if following conditions are true:
A Remote Assistance connection could not be established. You may want to check for network issues or determine if the invitation expired or was cancelled by the person who sent it.
This problem occurs because of an error in RDC 6.0 in Windows XP. When you use the Remote Assistance utility on a Windows XP-based computer that has RDC 6.0 installed, the Remote Assistance session tries to connect to the novice’s computer according to the first IP address in the Remote Assistance invitation. If the Remote Assistance session cannot connect to the novice’s computer according to the first IP address, the Remote Assistance session does not reference the other IP addresses in the invitation. Therefore, this problem occurs.
