@Marcos I apologize, but I'm not sure exactly what you are suggesting. As I said, I am not experienced with all of the settings in ESET (or other Firewalls in general). If the Firewall is paused already, what other setting would work? I have tried adding rules to open the appropriate ports for GoToMeeting (TCP/UDP), I have tried excluding the application from protocol filtering and I have tried to allow the GoToMeeting web sites and I have tried allowing the GoToMeeting addresses. None of those seem to make any difference. What is the pre-release update channel?
@itman I tried to allow traffic to g2mcomm.exe. It has not seemed to help.
Thank you to both for your ideas. This has been very time consuming and very frustrating thus far.
