Summary: One common problem connecting with Remote Assistance typically involves a router 'getting in the way'. I get the message: 'Remote Assistance connection could not be established because the remote host name could not be resolved.' - What does that mean? • Essentially it just means that remote assistance didn't get a response from the target computer. The most likely cause in home scenarios is that there's a router in the way at the remote site. For Remote assistance to work, port 3389 must be forwarded on that router to the target computer's internal IP address. • Recent Comments
This don't work, cause if I change the IP address the assistant don't ask me more for a password. I get an error message "There is a problem with the invitation and it cannot be opened." I the ip is protected by hashing the ip address. Posted by: lasombra at July 23, 2007 02:34 AMOK, this is simple. I'll make this as easy as I can to understand. 1) Open port 3389 on both the firewalls for each user. If there is only 1 firewall on one end and not on the other, then you only have to open the one firewall up. 2) The file that is created for the session invite needs to be edited in 2 ways. RCTICKET="65538,1,192.168.1.1:3389;host_name:3389 This line needs to be changed in 2 spots: RCTICKET="65538,1,66.66.66.66:3389;host_name.172.16.1.10:3389 You need to change the internal IP address to the external address, i.e. LAN Address to the WAN address, and you need to ADD the user default gateway to the end of the host_name. So, they should be changed like this: RCTICKET="65538,1,192.168.1.1:3389;host_name:3389 to RCTICKET="65538,1,66.245.112.159:3389;sandi.172.16.1.10:3389 I can't make it any more simply than that. Hope that helps you all.

What can i do to fix problem!! please HELP This page has good explanations for most of the ways Remote Assistance can go wrong (including port forwarding with NAT, connecting behind firewalls, through routers, etc), and solutions: http://www.petri.co.il/what's_remote_assistanc.htm Posted by: Joe Marty at January 9, 2008 06:47 AMI have followed the information given by Steve in August 07. It did not work, posibly because I am using Vista as is the remote computer. Does anybody know how the format of the invitation Ticket varies between XP and Vista?
