I have a Dell 1750 PowerEdge Server running Win2000 with 2 Ethernet interfaces and 2 USB interfaces. The "hostname" is tied to one of the Ethernet interfaces. So ping "hostname" returns the Ethernet interface's IP. However, when I plug in the USB Linksys wireless adaptor, ping "hostname" returns the IP of the USB interface! If I disable the USB interface, ping "hostname" reverts to the Ethernet interface IP. I have applications that rely on "hostname" and they break when Linksys USB adaptor is activated. Any clues ? Appreciate any info on this.
