Thanks for all the input.
I installed UltraVNC and set up a DDNS service, but found it a bother to configure. I have admin rights but was unable to change the password for VNC. I was also concerned about security. Last time I used a DDNS service my account was terminated by the supplier for 'repeated access attempts' or something similar. Next day my computer suffered a massive catastrophic failure, I had to replace the motherboard and hard drive. Not sure if the two were related but I thought I may have been the victim of some sort of attack.
Next downloaded and installedGoToMyPc.
Flawless, I can connect from my laptop using a broadband USB dongle with very little lag.
Not to mention the security is probably much better than VNC.
Annual subscription at $180 is pretty good value. (I spend $600 a day on fuel)
