Easy Remote Assistance?

[Michael Potter]

Hey everyone,

I need some way to easily access and control other computers over the 
Internet with VERY little work required on the client computer. The people 
whose computers I will be controlling are computer illiterate and will not 
know how to open up ports if their computer is protected by a firewall. All 
the systems involved will be Windows systems. I need to have the VNC Server 
configured for each client so that the default port used is port 80. I know 
that the registry can be configured to operate VNC through port 80. 
Basically, I want to offer each client a downloadable package with brief 
instructions. The package would include the VNC Server install file and a 
registry file that will automatically change the appropriate registry keys 
after installation to allow their server to run through port 80. My question 
is how can I create those registry files that automatically make changes to 
the registry so that they won't need to manually edit it? Secondly, will 
distributing the "package" that I intend to create work over firewalls? 
Finally, if these users are on a LAN with a residential gateway/firewall, 
how can I detect their WAN's IP easily? Is there some software or website 
that they could visit to tell them their actual IP is? The steps that each 
person would (hopefully) be able to take are:

1. Download RealVNC and install it as a system service.

2. Run a registry batch file that disabled automatic port configuration and 
sets the port to be used by VNC to port 80.

3. Launch the VNC Server application and set a password.

4. Relay their actual IP to me using some sort of software/website.

5. I use VNC Viewer to connect to that IP over port 80

I assume that I would have to append their IP with ": -5820" (-5820 + 5900 = 
80) in order to connect to their server through port 80 (i.e. 
123.456.789.000: -5820). Any help with this would be greatly appreciated. 
The net affect of all of this is to create a simple package similar to 
DesktopStreaming's technology -- in fact, all users of that service have to 
do is download a small applet, and the technician can control your 
computer...
