Okay, your cables are connected as correctly as far as I can tell. Other thing does your pc networkcard have led that signals that your network cable is connected? Or does your windows say something if you unplug your cable(it's safe to do)?
Where is the AE Update?
You can find AE update for windows form here
You can also find some info about AE networking from here
I don't see anything about enable/disable a cable connection.
Okay that was assumable, just wanted to check.
Under the Network tab in my Airport settings panel, should "Distribute IP Addressing" be checked? I did this before and all it did was disable the internet to my PowerBook. If it's supposed to be checked, should I change anything on it or on my PC?
Before you do anything you should collect some info, On your powerbook, open System preferences\
etwork\\airport\\tcp/ip, you should try to remember every value there. So those values can be used afterwards.
I think that your ISP gives you only one ip address, so you need to have NAT to masquerade those two connections, so your AE takes that one ip address that your ISP gives, and then creates subnetwork behind that and routes traffic to your ISP this way your ISP sees only one machine(AE).
If that assumption was correct, "Distribute IP Addressing" should be checked, and, yes, all your computers may lose their connections momentarily, but now your LAN should start working!
With "Distribute IP Addressing" and "Share a single IP address(using DHCP and NAT)" selected. Addressing space can be what you prefer. Now with those settings turned on try to "repair" in windows network settings. Hopefully it should now give you an IP address that is in that range you just selected. Also your mac should now have new IP address within that range. Now those computers should be able to communicate together, simplest way to test that is in windows to PING your PB as described before.
Next, open Internet tab in AE preferences (I hope your ISP is using TCP/IP networking) and set your "Connect using" to Ethernet and "Configure" using DHCP, it should get same/similar values that you collected earlier from your PB. You might need to fill DNS servers, domain name and dhcp client id, your self, use same values your PB had earlier.
Hopefully your network is working now!
