I am working here on a windows XP home sp2 edition to solve a networking problem. I have DHCP server and internet router. When starting up Windows XP the network card sends a DHCP request and gets its address correctly which is 172.23.56.25/24. With the windows firewall which is actually disabled I am trying to ping another host in the same subnet without success. I can ping my own network address and the localhost but no other hosts where I am shure that they respond to ICMP. When starting up with a knoppix Linux there is no problem with the network card. I have also tried another network card but without success. Could you help me on this ?
