I love these discussions. I think most of these are the same. It is just up to each person to decide what works for them. RWW on Small Business Server was and still is fast and extremely secure and allows quick connectivity to all computers. Before SBS 2008, you were not using an SSL connection and needed port 3389 unless you changed it so it was not very secure. Plus, you had to use port forwarding, not always simple with a Cisco router. Now all that has changed.
Again, though, LogMeIn is fine and so are VPNs and VNC. A lot of it is what you know how to set up. What is simple to Sandeep is very complicated to others. This is why LMI is so popular. I would have to bet that wwpp has McAfee on his computer if LMI didn't work.
Anyway, RDP is still the cheapest and fastest way to go, although who knows how fast. The cool thing is if you have a 2008 server with a public certificate, you can set up RDP to easily and safely connect to your computer. But, the cool thing is if you have 20 clients, you can just use the drop down box, pick or add a computer by NAME on your network and you will be connected to that computer. You don't need any software on that computer like LMI or GTMP. So, if your computer were named Billing, you just put Billing in there, and it will go to that computer. *
