I am able to offer Assistance from Win 7 to XP without issue. But when I try to offer assistance to another Win 7 I get the quick error that you cannot connect. This has all the group policy and permission I think to make this work.

Hi, Please let me know how does the issue occur, right after you click "Invite someone you trust to help you", or when you select any option to send an invitation. Are there any errors received? Does the Remote Desktop work? You can exchange the destination and source PC. I suggest you log on with a local user account but not a domain account on both computers, verify the related policy and then try to launch Remote Assistance. If it works, check GPOs on your domain controller, find the GPO that changes this policy. If any Security Software or firewall is running, temporary disable it to check the result.
