Answer : cannot activate remote access in windows live messenger

Actually "Request Remote Assistance" requires that the router at the site that is asking for assistance must have UPnP enabled on the router. There is a "ticket" generated with the request. The ticket contains the current public IP address, and also the LAN IP so that the support person can locate locate their PC from the remote site (this is automatic). Because the problematic PC is behind a router, the only way for the software to collect the public IP is through UPnP. Logon to the router and see if you can locate and enable.
