OK - I was able to test inside the building today. Using my Linux (F17)
laptop, and getting a DHCP assigned IP address. Ping works to all hosts
normally, and I am also able to resolve all DNS host names as expected.

RDP sessions still fail however. They either connect and hang after a
few seconds, or they simply don't connect at all. It's exactly the same
symptoms as when connected via the VPN. Clearly, there's some sort of
issue with both gnome-rdp and Reminna.

So, in this case, my nsswitch.conf has files, dns as its entry (which is
the default).

We're not using local host files for name resolution. Too much work when
you have a valid DNS server already handling that for you. I generally
only modify /etc/hosts as a last resort.

So I think there actually are probably two issues here - one with
Network Manager / vpnc, and the other with RDP sessions in general.
Again, my Windows clients - both physical systems and VMs - are working
just fine from both inside the building and via the VPN. It's
specifically Network Manager and gnome-rdp / Reminna that are having
issues.

Hope that helps a little more!
