Indy,
Thanks for your input. I checked the permission today, It is set up for everyone. I did not want to mess more with that. I think I will try to uninsall amazing chart on the client pc with xp and reinstall it. it might solve the problem. I am not sure I need to ping the main pc, because the network is working other then AC. I can see all machines on the network form either computer. Does his make sense?
I am sure it something very silly that cause to problem.
I wish Ac team have some guidelines reguarding setup networking. Things must do and things must not do as well as a written insutruction to troubleshouting this issues.I will keep trying. If you have another clue let me know. Thanks
