It would sound like you simply have LMI connected so that your second office can connect to the main office. VPN would be rather slow.
It would be helpful to know what you are using for hardware, e.g.
Servers or workstations, Client/Server at each office or C/S at main office and peer to peer at remote office. Switch? If so, speed. Router/firewall. If server, what OS. Workstations/Clients what OS.
RDC is not that hard to set up and there are many on the board who can help or log in to your computer. LMI is good, but unless you have LMI ignition, it will be much slow to start than RDC. RDC is also a bit more secure.
Please give more detail than "able to link the two sites." I am assuming that your remote office has, say, eight workstations in a network environment. Your main office has a networked environment either Client/Server or P2P. The main computer has SQL and all your clients connect to it. You are trying or have connected the remote office to the main computer using LMI. That seems rather easy. Can you explain EXACTLY how the remote clients are connecting. To client computers on the main office? Directly to the main computer on the main office? Does each office have physicians or staff working at the clients? This is very important.
