I have a vpn set up for one branch to another where there is one user in the branch office who vpns into the main office. The vpn was working fine but his pc has now changed to a Win7 64bit pc. Remote desktop to the main office has stopped working all of a sudden on this new pc. It was working fine for a few days and now does not anymore.
I can ping the ip of the main office from the branch and viceversa but no rdp. None of the settings have changed. Our network engineer has confirmed that the VPN tunnel is fine and passing data. The main office pc can be rdp'd from any pc in the main office including a win 7 64-bit pc so I dont think its 64-bit related.
I have shut down all firewalls and and removed the antivirus from the pc but still cannot rdp.
