Just a little addition. I think I have the issue narowed down. My cousin
can access the sites through win2k, and linux but not through win98, the
clients that can't access it are also useing win98. As crazy as it
sounds I think it's a windows 98 problem accessing dns even through the
firewall even though the proper ports are open. Any ideas?
