(sorry, if you have read this twice, earlier I replied to a post I was reading instead of setting up a new thread).....
I setup a mini P2P wireless network using XP (host) & Win2000 (client).
Initially I only wanted to share files so I did not enable ICS. I got the sharing to work eventually and it works well (File and Printer sharing).
Then, I decided to enable ICS. IP addresses changed from 169.x.x.x to 192.x.x.x. Fine, did some DNS changes and managed to get the PC's pinging each other and even got the client pinging the web, but could not browse the websites or connect to shared directories. I gave up on ICS and downloaded:
Changed the IP addresses to 10.0.0.1(server) and 10.0.0.2 (client).
Now I can access the web from the client, can ping both ways but still cannot access the shared folders.
Any ideas? Ideally ICS sharing the web plus the internal network is what I need.
