Hello,

I've been trying to get NetworkManager to work with my university's VPN
(which uses PPTP) for ages and I was reading through a similar thread on
the mailing list and was wandering if you could help me diagnose, and
hopefully remedy my problem.

I am using the settings that appear to work fine on Windows Vista and
also have previously been reported to work on an earlier version of
NetworkManager and Ubuntu (from a pdf file provided to my university by
a student, who had success and created a guide).

The output of /var/log/messages is as follows:
