Hi,

I'm having trouble with my MDA Vario III / HTC Kaiser running WM6.0 when making a connection to my office VPN (PPTP). I have to connect to the VPN to access the Exchange server. However, my IT people tell me that the phone is grabbing multiple IP addresses, so many that they have to eventually kill my access to the VPN.

I stopped using Direct Push, but even when the phone is scheduled to connect every 15 mins, the problem still occurs.

Can anyone suggest what's going here, and what the solution might be?

Thanks,

Jon.

Something seems to be wrong with your networking drivers on your phone. Mine doesn't grab multiple IP addresses just one and it keeps getting the same one in accordance to lease time settings on my DHCP Server and Firewall.

Thanks - your reply set me thinking, so I dug into the registry. The key relating to the VPN connection had 'EnableDHCP=0', this despite the fact that the connection is set to 'Use server-assigned IP address'. I've manually set it to 1, and I'll test tomorrow when I can talk to my IT people.

This is a real headache. The problem seems to be that the VPN connection refuses to use DHCP, even when I toggle the registry setting that I mentioned. If anyone has any ideas I'd like to hear them.
