MS Proxy 2, DHCP, and PPPoE

[slunk]

I'm trying to help a friend with a problem he has at work, but I have little knowledge when it comes to such questions. They have an NT 4 Server running with 9 Win98se and 2 Win2000 Pro clients. Their internet connection is through Prodigy DSL. It was just switched from static IP to DHCP because Prodigy doesn't provide static IP anymore. They also have their PPPoE software running on the Server. The problem is: during the day they lose the connection a few times. The NT event viewer log shows ID 1003, DHCP Client could not obtain an IP address. During the downtime, the modem is working fine, but the computers cannot gain internet access. I believe that Proxy is blocking the DHCP server from obtaining the address after the lease expires. Is there a setting in Proxy allowing him to grant permission for a specific IP address to communicate freely, without being controlled by Proxy? Or is it possibly something else we're missing?

Okay, I'm starting to understand this a little better now. I know when PPPoE is present, DHCP isn't present. Two totally different things. But why does NT act like it's using DHCP? Anybody got any answers on what address I need to allow Proxy to bypass???

Could you be clearer about the network? and don't worrry about the PPP0E. You mentioned Proxy. Is it MS-Proxy server? So far I understand that the network consists of 1 NT server and 11 clients. What else is in there?
