China DOS Union

Two machines, 2003 and 98.
In 2003 I can access the shared resources on 98 through Network Neighborhood. But on 98, when accessing the shared resources on 2003, it says "Cannot access. No permission."
What should I do???

Enable the Guest account.

This problem has already been solved.
But now 98 still can't get online through 2003 sharing? I'm using a crossover cable to connect them. The settings on 98 are
ip:192.168.02;
mask.255.255.255.0;
gateway.192.168.0.1;
DNS.192.168.0.1;
WINS.192.168.0.1;
There are no settings in 2003. Based on my previous experience in XP, this should make shared Internet access work. But now when I open the browser in 98, it brings up the Internet Connection Wizard. What should I do???
