I am running a Windows Server 2003 SP2 domain with 2 domain controllers and mostly XP workstations. I have been installing a few Windows 7 machines and I cannot remote assistance to them from any machine - XP, Vista or other Windows 7. I know RA from XP to 7 is not supported but 7 to 7 is not working. I get the generic "your offer to help could not be sent". The Windows 7 machines can offer RA to any windows XP machine with no problems. Windows Firewall is disabled and I have tried:
Adding helpers in GP as "domain\username" instead of just "username"
installing this patch: http://support.microsoft.com/kb/2003088#top
on both DCs
I would prefer to stick with windows built in remote assistance rather then go to a 3rd if possible. Upgrading to Windows Server 2008 is not a possibility right now. Thank you, experts!
