Thanks to everyone for their suggestions. I did make sure WINXP did not have the built in firewall running and WIN98SE did not have Zone Alarm (actually I uninstalled it, it was an old version). I did make an error in my last post, I am using 192.168.0.1. I have all folders shared with unlimited access. I am going to take Kyle Elmblade´s suggestion Monday and return the NIC for another one... it is very difficult to get quality products here in North Brazil, and indeed... the NIC card in the box did NOT match the instructions or the brand on the box, it was probably used! My client bought this one, but I will return it for exchange! Again, thanks again, I will keep everyone posted to the results.
