I have a proxy server running on win2k, and it has two nics. one connected to the modem, and one to the internal network. There's the dhcp server which which hands out the IPs. THe nic to the modem has a lease that always expires in a week, or sometimes an hour. When the lease expires, the clients in the internal network can't reach the internet. Is there a way I can configure the lease so it won't expire. My ISP is Comcast also....If there are more things I should clear up than tell me. I would love to fix this problem.. I've tried to flush, release..and nothing works.....
