:-) Its been a few days since I logged and since I last read this thread I have started to use Teamviewer.

My ISP updated the firmware of my router which disabled/removed DDNS. So I gave Teamviewer a try. Its great! It just works, no account required and its free! I have even started to use it using my Android phone. It's often said if things sound too good to be true then they usually are. Teamviewer is an exception, as I was told many times.

I didn't know this. It now means I can play eXtreme gammon for free on the PC :-)

Thanks for the help guys, and for anyone reading this post because they are wriggling around with IP addresses, DDNS and Windows Remote Desktop just save yourself a few hours and install Teamviewer!
