We are running VPN and geting disconnects every 10 minutes. IPCONFIG /ALL reveals that the DHCP lease is being issued for 10 minutes only. I cannot find where the DHCP lease durations are kept. I am using Windows 2000 Server. Many thanks. The IP address that I am refering to is the Static address, not the VPN client address. That is to say, that address that the router gives out to the Server, behind the firewall. The router does not have any settings that issue the address for a period of time.
