Shared Internet Connection on client computer

[William]

Help Me I'm Melting!!!!
I'v got a wirless network. Host computer and 2 client
computers. The host computer always connects to the
internet just fine. The shared internet connection
stopped working on the client computers about 4 weeks
ago. Ran Network wizard many times. Ping test is good.
The strange thing is that if I use a different ISP dial
up (problem is with prodigy) all works well. I can see
the internet gateway is connected in network connections.
All computers have all service pack upgrades, driver
upgrades. I have verified there to be no IP Addres
conflicts.
Got about 50 hrs into this.....
Pulling my hair out!!!
Heeeeeelp

it could be the DNS issue. can you ping a public IP? If yes, can you ping a
web site by name like ping yahoo.com?

Hello Robert,
The client can ping 66.94.231.98 (yahoo)
successfully.The client can not ping http://www.yahoo.com
sucessfully until the host computer pings
http://www.yahoo.com. Once the host sucessfully pings the
name, the client works great!.
When a new dial up connection is established on the
host, the above pinging proceedure must be repeated.
One more thing, the host is running XP Home upgraded
from Win98. The client is XP home.

I'm looking forward to your response for a solution as
I feel I have made more progres the last hour, than I
have in the past 4 weeks.
