[nfbcs] Does anyone know if it matters?

[Jack Heim]

Right, just to clarify, the host name comes from the IP address, not the 
other way around. When a machine joins a network, itgets an IP address 
one way or another. It could be assigned one via DHCP or have one 
statically assigned in the operating system. Either way, that IP address 
determines the host name. If the machine thinks it has some other host 
name, it's just wrong. However, Windows used to use the machine name, it 
would not properly be called the host name, as an identifier for the 
wins/netbios protocol. So then the machine name you typed into the 
networking configuration on your Windows machine would matter. I kind of 
doubt that a typical home network would use wins/netbios though.
