We have a share desktop problem with Office Communicator 2007 R2.
Office Communicator 2007 R2 works fine across all sites with instant messaging.
However, the share desktop function with Office Communicator only works across the LAN, currently it will not work across the WAN (Leased line between all sites). We also have an ADSL connection at each site but this only routes traffic that is required to go to external locations such as the internet.
The problem we are having is not specific to any desktop o/s.
The Office Communicator Server is located within one of our sites, and we assume it's not a bandwidth/speed issue as Live Meeting works fine across sites even when sharing a desktop & carrying out a VTC call from the same system.
As Office Communicator uses random ports (to my knowledge) I have checked with my colleagues that there are no ports blocked on the Cisco firewall – this has been confirmed to be the case for all inter-site links.
Remote desktop, VNC and Live Meeting shared desktop all work fine across the WAN, just not Office communicator share desktop which is the company preferred option.
Any help would be greatly appreciated
