I am also very much interested in VPN (I think IPSec) in WM 2003. movianVPN is my main choice, since I am more familiar with it, so movian not working is disappointing to hear.
I did find some confusing info online though:
"Windows Mobile 2003 includes many new features specifically for the enterprise, such as new VPN (Virtual Private Networking) support, IPv6, enhanced synchronization, device management, and more. In case you missed it, Windows Mobile 2003 is reviewed in this issue on page 14.
...
Microsoft continues to support PPTP (Point to Point Tunneling Protocol) in their VPN client for Windows Mobile. In addition, Microsoft has added IPSec/L2TP—IP Security, and Layer2 Tunneling Protocol —to its Windows Mobile VPN client."

Can anyone verify this?
