Server 2008 R2 Routing and Remote Access PPTP VPN issues
Hello,
Some of my users are having problems connecting via routing and remote access PPTP VPN, I myself never experience this issue however many users appear to be disconnecting and having to redial the VPN almost 10 times before it remains connected so they could carry on their work. Nothing obvious in event logs, any ideas what could be causing this?
Thanks,
Mark

Check if that happens more often while more than one connection is used. It sounds like an issue with GRE session IDs and NAT - in particular if there is a firewall/router in front of the server. It's always best to have the VPN device directly connected to the WAN/Internet.

Thanks I have enabled logging and now waiting for the connections to start dropping.

Qlemo, please can you clarify on the GRE session IDs and NAT comment? this doesnt seem to affect all users, I for example cannot replicate this fault however 2 users on site regulary appear to be affected by this.
I have reviewed the logs, I might be missing something but I cannot see anything obvious at this point.
Cheers
