Management Central Server Won't Start -- MIDRANGE-L

Sometimes, when I try to perform an iNav (V5R3 on an OS at V5R1) function,
such as Configuration and Services...Fixes Inventory, iNav times out because
it cannot connect to the central server (we only have one System i). I saw
that the *MGTC server wasn't running (duh) so I started it. No dice.

A judicous (I hope) search of the archives and other sources pointed me to
the fact that TCP probably was not configured properly.

My previous employer let me look at and print its TCP configuration so that
I could do a comparison.

Before I go further, allow me to explain that the DNS at the previous
employer was on a Windows server (2003). The DNS here is at Comcast.Net. I
have looked at the "cabling," and I just get confused. Those of you that
know me (you know who you are, don't lie) know that I'm no network or
sysadmin guy.

Below is our current configuration (bear in mind that 123.456.78.241 is an
obfuscated IP address for obvious reasons).

My only thought, after looking at the previous employer's set-up, was

to change the Domain definitions to:

====================================================================

Change TCP/IP Domain (CHGTCPDMN)

Type choices, press Enter.

Host name . . . . . . . . . . . 'DTO' [<--Change]

Domain name . . . . . . . . . . 'DTO.LOCAL' [<--Change]

Domain search list . . . . . . . *DFT

Host name search priority . . . *REMOTE *REMOTE, *LOCAL

Domain name server:

Internet address . . . . . . . *NONE [???]

====================================================================

Even if I am on the right track so far, I have no idea what to change the
Domain name server's Internet Address.

I do know that, if I run PING MIDRANGE.COM from the System i, I get "Unknown
host" as the reply. Though doing so in the Windows CMD Prompt works fine.

I would rather not go making changes willy-nilly to see what, if anything,
works. Saw a guy do that years ago; we had to reload the system from a
backup tape.

Of course, I could leave well enough alone. Most of the functions that I
use regularly in iNav work fine, though this change might also allow me to
use Netserver to map an IFS folder to a network drive in Windows Explorer.
