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

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.

I recommend using the names and not the IP address.  There are some
extremely rare conditions to use the ip address.  One has to do with
tricking the Code/400 Project organizer.  And I forget the other cases.
But we've changed our IP address and you don't want to have to change all
your clients.  Trust me.  Our original addresses were picked by someone
(who no longer works here) who thought these were reserved.  However we've
discovered that 198. addresses are not and you should see the site with the
duplicate ip address to what we've had.

Don't forget to add the DNS entry to CFGTCP-12.  Then you should be able to
ping by name from your 400 using the PING command.

Ok, I'm learning much more about networking than I wanted to, but
unfortunately it is necessary.  If you don't mind, couple of more questions
before I sit down with the networking person:

First off, we are running DNS on a W2K server.

Second, just so I understand this correctly, having the address of the DNS
server on a particular computer allows that computer to resolve names, but
does not help other computers to resolve a name to this computer?  That is
the function of the DNS.

Next, how does the DNS server know all the names on the network?  Is there
an equivalent to the HOSTS file that should contain all the names?  Is this
maintained manually or by some automatic means?

Also, in going around trying the resolve the problems, I noticed that he
had
setup most of the machines with the AS/400's IP address instead of the
name,
which explains why some were having problems and others weren't.  Is there
an advantage one way or another?

Many thanks again for all your help!
Rick
