Hi, I'm pulling my hair out on this one. Windows is mapping my computer name "CHRIS" to 127.0.0.1. I need it to map to the "true" ip address of my nic card, 192.168.12.20. e.g. a listing (using java) of interface names to ip addresses: Interface: MC TCP Loopback Interface CHRIS 127.0.0.1 Interface: Broadcom NeXtream Gigabit Ehternet Driver 192.168.12.20 192.168.12.20 I have another win2k computer where the mapping is being done correctly. Interface: MC TCP Loopback Interface 127.0.01 127.0.0.1 Interface: Broadcom NeXtream Gigabit Ethernet Driver ROCK 192.168.12.20 I've modified the hosts file, but no luck. It still doesn't resolve correctly. Disabling dnsclient doesn't work. ipconfig /flushdns, ipconfig /registerdns, ipconfig /displaydns works, but has no impact on the java display. I don't believe it's a java problem (java 1.4) because it's working fine on the second computer. I also believe some closed source C code is coming up with the same result on the "bad" computer. Any help much appreciated! Chris
