I've configured sstp vpn on a tmg cluster several months ago and it worked fine. I followed mainly isaserver.org way to setup all.

Recently it stopped working and remote clients just say Error 0x800703e3 The I/O operation has been aborted because of either a thread exit or an application request.

L2tp works fine.

The listener is bound to the default cluster ip and other listeners are bound to different ip addresses.

The certificates are private, but valid (so it seems to me). Clients have their own certificates from the same CA and crls are published externally, delta crl too.

Tmg system is a cluster of 2 3 leg servers, joined to a domain and integrated with Exchange Edge and Forefront Protection for Exchange.

I cannot find documents on this error relating to tmg vpns.

Can You suggest me how to diagnose the problem on the server side? How to search?

Thanks,

Stefano
