Provided that both the Mac and the PC are on the same subnet, that would mean that you do not have network connectivity. It may be time to try that crossover cable, or better yet a hub or switch. Check your network preferences on the Mac and choose Network Status in the Show: box if the ethernet port is showing red, then you are not networked. If you are getting a green light then the Mac and PC are trying to make network and the Mac is successfully making its port a crossover port. My instinct is that you will see a red status. If this is the case there may be one other trick that you could try. It might be possible that the NICs are having problems negotiating there link speed and duplex. You may want to hard code these settings to eliminate auto negotiation as a problem. It may be a little slower, but I would try using 100/Half. On the Mac if you are running 10.3, you can go to the network preferences for your built-in ethernet and choose the ethernet tab - change Configure: from Automatically to Manually, change Speed: from autoselect to 100BaseTX, and set Duplex: to half-duplex if it did not default to that. You will need to hard code these on the PC as well using the configure adaptor. It will be under the advanced tab, depending on the vendor of the NIC, you may either see link speed and duplex as a single setting, and choose 100/Half or there will be a seperate setting for the link speed and the duplex setting, if that is the case set the link speed to 100 and duplex to half-duplex. After this if you do not see a green link light on the PC's NIC anb a green status on the Network Preference Status screen for your ethernet connection on the Mac, then you will need to either get a crossover cable, or a hub or switch. If you are not getting a network link on both machines, then they will not be able to communicate on the network. Once both machines can get a network connection, then you can try the other steps, I mentioned previously.
If you are getting a good connection. make sure both machines are on the same subnet, for example assign the Mac an IP address of 192.168.1.4 with a 24 bit mask (255.255.255.0 subnet mask) and assign the PC an IP address of 192.168.1.5 with the same subnet mask 255.255.255.0.
I hope this helps.
