Mac on PC network resets internet

Specs: Windows XP, P4 3Ghz/2gig RAM
So I have an unsual network setup but its worked fine for a while until now. I have a ADSL Speedstream modem connected to my main PC. My PC acts as a hub which other machines connect to. So the modem connects to the onboard network input on the motherboard which is a Asus P4P800SE. I have an Asus Access point PCI card with an external antenna and that connects wirelessly to a PS3, a Dell laptop and a newer Imac. I also have a Dlink PCI network card which connects to an much older Imac (CRT monitor one) and its a wired connection.

So in the Network Connections under Broadband I have the PPPoe Icon which connects to my ISP then I setup a network bridge which has the modem (onboard ethernet), Dlink ethernet (old Imac) and the wireless AP card.

This setup has worked for a while and still does work even when I reinstalled XP with the SP3 version. My problem I am having is that the old iMac (wired) is in sleep mode when not in use so when someone uses it and it comes out of sleep mode, the internet on my main machine disconnects and reconnects. The power management tab on the Dlink ethernet are all unchecked so its not that. Are there other setting to consider now that I use SP3 instead of the older XP I had? Its just annoying to have the Imac disrupt the entire network by resetting my internet.

"the internet on my main machine disconnects and reconnects"

If you want you can start to diag that issue. See event logs.

I would run Analogx's free proxy on the PPPoe computer.

"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

Thanks for your reply. I should try out that program you suggested.

Anyways there seem to be 2 types of errors i see on the event viewer list.
Red X Error: IPNATHLP "The DNS proxy agent was unable to read the local list of name-resolution servers from the registry. The data is the error code."

Yellow triangle warning: Tcpip "TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts."
