RE: Help! Network no longer recognizes AS/400 hostname

The advice to use names and not addresses is definitely the way to go.
The host file is a pain to maintain, it is much nicer to have every
machine in the network use the same DNS server.  But if you are using a
DHCP server to assign address to devices on your network, you should
also use dynamic DNS so when the DHCP server hands out an address, the
computer name and the handed out address are registered in the DNS
server.  So every time a computer attaches to the network its name can
be resolved even if it gets a different IP address.  Most people assign
static IP addresses to servers, printers, etc.  Another way to assign a
"permanent" IP address to a device is to set up a reservation in the
DHCP server.  Basically the DHCP server can be told to look at a MAC
address (a 12 digit address specific to the network card, although there
are ways to clone a MAC address and for good purposes) and ALWAYS assign
a certain IP address to the MAC address.  The reservation also insures
the IP address will not be given to someone else.

By jove I think you have it.  The rain in Spain falls mainly on the
plain.

The DNS is maintained manually.  Think of it like a shared hosts file.
