Yea a question I can help answer not get answered! Being a network admin not a programmer I have used this forum many times for help with my code. Tell me if I have this wrong!
It sounds like you are running a web server on one PC, and you are running a internet sharing program on the other so that it may connect to the web. This is where the headaches will begin for you. What program are you using to share you net connection? Is it the wonderful internet connection sharing that comes with windows? This Is what is going on regardless of what software you are using.

[Your server]
This is a bit of a lesson on networking; everything on a network uses a port. Think of it this way your IP address is your street address and the port is a door on your house. If you are trying to run a web server the port you need open by default is 80. Now the trick is getting your PC/Router to do port forwarding of port 90 to your server. This is easy in some and can’t be done in others. The best way to fix your issue is to buy a router. Then hook both computers to the router. Then run port forwarding or as I do DMZ (De-Militarized Zone) DMZ is the best way if you are going to host other things besides your web server. Well if you don’t want to by the router tell me how you are sharing your internet connection.
