I have an office that is running a domain. They have a TP-LInk TL-600VPN. This office is opening up another location and wants to work on applications/databases of the domain server at the original location from this new location. What do I have to do to set this up. There will be only 1 computer at the new location. They do not want to do anyhting like GotoMyPC of logmein, they want to actually access the databases and work on them from this one computer.
Make sure that the bandwidth between the sites will give you reasonable performance. What do you have for upload and download speeds at each location? You may go through the trouble only to find that it's not responsive enough.
If you will always have only one remote computer at the remote location, consider setting up a VPN to the server, if nothing else as a test of performance. You shouldn't need to spend money on software or hardware to try this.
What is the objection to LogMeIn or GoToMyPC? I have often set up VNC (free or $30 one-time cost with security) to an extra computer to accomplish such things. Since keystrokes, mousestrokes, and screens are all that get transmitted, performance may be much better.
