Great solution for LAN support. If you just have one location, a VPN o can modify setting on your router/firewall, tightVNC is your solution: easy to use and install, really fast and good quality and FREE
We have been using TightVNC several years in our central office (around 50 computers, call center, warehouse, design) to provide support to our employees and TightVNC works really well. Once installed, it's really fast to connect and gives a great image quality and responsiviness. Also it's a free software, so it really worths the time you should use to configure it
The main reason we stop using tightVNC to go to teamviewer was the opening of several outside warehouse, franchises and stores. In order to continue using tightVNC we should open different ports to any computer and as more and more people start using laptops outside our LAN, makes impossible to continue using it without a VPN. The main lack we have found it's the lack to file transfer in an easy way (copy/paste, drag and drop). If the remote computer has several screens it's not so comfortable because you must scroll
