In my office I have VPN connection, our office branches are in London, Kuwait, South Africa, Switzerland and Germany, sometimes I need to access users Laptop and PCs to fix their problems
Can you please help me how can I access users Laptop and Desktop thorough VPN.
:confused:

Quick method on the remote computer is to turn on remote desktop.

I would agree with yodatech. If you are not running systems that Remote Desktop is not a viable option, you can also look at RAdmin Famatech Website (http://www.famatch.com) . They do have licensing fees. Also, you could use Real VNC, which is free for basic use or for a more secure edition, you would be charged a little fee . Their addess is RealVNC remote control software (http://www.realvnc.com)

Hope this helps as well.
