To prevent users from installing [i]GoToMyPC[/i] on their computers, the user has to be a restricted user, which, in many cases, isn't the best scenario. In many companies (including mine), there's good reason to give most users administrative privileges, in which case, they can install this software, via the Internet, onto their computers so they can access it from the outside.
If any of my users are approved for outside access, and many are, I want them to go through the established VPN, not some third party software that circumvents the process of approving and defining those users, and configuring the VPN accordingly. Moreover, these users can then access their HOME computers from work, doing day-trading in the stock market, surfing for porn, or whatever else they might do from home, all bypassing any company safeguards or policies.
There is a way to block [i]GoToMyPC[/i] in a router, but those [b]EVIL people[/b] at [i]GoToMyPC[/i] can, and do, change IP addresses at will, thereby circumventing any router block a company might define. Every time I see a way to block them, I see something else they do to get around it.
The bottom line is that the company, not the users -- [b]and especially not any third-party company like [i]GoToMyPC[/i][/b] -- should decide who has remote access to and from the company computers; and [i]GoToMyPC[/i] is designed to do just that.
It's kinda' like the radar detector of remote access software, and I'm the highway patrolman trying to keep them from speeding on my little corner of the information superhighway.
