I have seen this done with UltraVNC and have no idea how to go about configuring it. Hopefully someone can assist.
I have seen several tech support companies have a .exe file where I would download and run the exe. Once I run it, the tech was able to connect to my machine to assist me troubleshoot various issue without me doing anything on my part. When I looked at the properties of these exe files, it said it's a "UltraVnc Self-Extract Setup" file.
I work for a company that would like to utilize this tool. So far in order to use it, we need to install it to the user's computer, configure password for VNC, and then set it through the firewall. Also each time when we want to connect, we have to ask the user for an IP address in order to connect (Dynamic IP address). This can be a long and tedious process. Another issue that we run into is that the user must have this installed on their machine already in order for us to assist them. Otherwise, we need to walk them through the installation.
So my question is how would I go about configuring UltraVNC so that if I sent the url to a user and they download the exe file, I should be able to connect to their PC to assist them without having the user make any changes to their system?
