I have two PCs - one with Win 7, Pro 32 bit and the other Win 7, Ultimate 64 bit. On the 32 bit machine I can easly provide Remote Assistance to others via a request coming in from Windows Live Messenger (ver 2009 - build 14.0.8089.726), but on the 64 bit machine I can 'accept' the incoming request and the person on the other end sees that I have accepted, but then nothing happens. I have checked my firewall and Remote Assistance is allowed [This feature allows users of this computer to request remote assistance from other users on the network. (Uses UPnP, SSDP, PNRP and Teredo)] I turned off Antivirus to see if that was blocking the outbound connection, but no help (on the 32 bit machine I have AVAST 4.8 home version and on the 64 bit machine 5.0.418). Any ideas? There are seven such items listed for 'Outbound Rules' under 'Windows Firewall with Advanced Security' - some for private and some for public network. This is a desktop and I am not on a public network. The remote assistance works find on the Professional 32 bit PC (much simpler on network settings).
