Problems Using a VPN Connection from South America
We have a couple of employees that routinely use a VPN connection to access files on a Windows 2003 domain. However, they are currently on a business trip in South America and have been unable to successfully log into the VPN. Is VPN access something that could be getting blocked by the Wifi networks they are using for internet access?

If that's what the wireless carriers are doing, what might be a way around this limitation?

Both employees have successfully used the VPN on previous business trips to SA. On this trip they say they have tried using the hotel wifi, a client's office wifi, as well as a Starbucks and they have all failed. Apparently the VPN connection initially says it's connected, but then the connection drops before they can access their email or files.
Since they have tried this from so many different locations, I think we can rule out the theory that ports 1701 & 1723 are being blocked by the ISP.

Too little information to tell. If you could be a bit more specific on the VPN type connection I may be able to help. IPsec obviously is the best and most robust VPN technology in deployment today for any Operating System. So rather then go cheap and use Microsoft VPN stuff which is full of security holes I invest in something robust. Unless security and robustness is not a concern. But then why use VPN in the first place. Just open up your network.

I hear what your saying. Perhaps a 3rd party VPN solution is the best way to prevent this from happening in the future. Would welcome your recommendations.
In the meantime, do you think it's possible that their internet connection is too slow and the VPN connection could be timing out? Maybe we could adjust the TTL setting on the server-side?

My comment is the correct solution.

On the server side, I believe the VPN was set up using the software that comes standard with Windows Server 2003. Is there more than one VPN option in Server 2003?
