Error 721

[Amir Marathonian]

Hi,

One of the employees tries to connect to our corporate VPN but he gets
"Error 721: The remote computer did not respond." Everyone else has no
problem connecting and also he was always able to connect. I read on Article
888201, that I should permit GRE protocol 47 and TCP traffic on port 1723 on
the network firewall. We don't use a firewall and also I checked the Input
Filters of WAN, under Routing and Remote Access, and I don't see anything
listed. Could someone tell me what I need to do?
What's puzzling for me is that he had never had this issue and we have not
made any changes to our network.

Thanks

Sounds as if the users ISP is blocking PPTP traffic, or the user has
introduced a firewall between the client and the internet connection.
