WORKAROUND
To work around this behavior, use any of the following methods.  Use Windows Messenger to establish the Remote Assistance session. This method will often succeed because of the reverse connection method that Windows Messenger uses. For more information about using Windows Messenger for Remote Assistance, click the following article number to view the article in the Microsoft Knowledge Base:

306556 How to obtain remote assistance using Windows Messenger

 Edit the Remote Assistance invitation file to reflect the correct port number that Remote Assistance is using:  Create a new invitation, and then save the invitation as a file. Open the file by using Notepad or another text editor. Find the &quot;RCTICKET=&quot; section. Note that this section looks similar to the following section

RCTICKET=&quot;65538,1,10.10.10.1:3389;user name.domain name.com:3389

where 10.10.10.1 is the IP address, user name.domain name.com is the fully qualified domain name or computer name, and 3389 is the port number.</li> Change the port number from 3389 to the port that Remote Desktop has been configured to use.</li> Save the file.</li> Send the invitation to the recipient.</li></ol> </li></ul>
