How do I to fix 2 Console reported errors in Mac OS 10.4.11

Question

When I start up my old G4 with OS 10.4.11, its Console reports
2 errors, as shown on the screen shot below
There are many "plists", so I do not know which one needs correcting.
In my System I located  "/en" here:
"~System/Library/Frameworks/Foundation,Framework/[symbol with a number unerneath}/Languages/en"
I recently had to to replace my high-speed Siemens DNS unit when it failed to power on.  My service provider
replaced it with a newer faster model which bears only the srvice provider's name (Telus), it is supposed to be
much faster and there was no charge for the replacement.  It seems to work fine to send stuff to my G4 and
MacBookAir., I do not know what "WIde Area Service Discovery" is, or how to fix that.  The DNS relay number
appears to be my computers address, I substituted some xxx's  to safeguard this address.in this post.

Re: What exactly solved my problems:
Thanks to your earlier reply citing even earlier discussions on thr same subject,
I followed the lead given in that post going to doug pennington
reply to jbtcat and looking at the websites mentionrd in these discussions, it was
all there, it informed me where to find the plists, why not to worry about
the WAN problem on my DNS unit ( I do not use a Wide Area Network), etc.
I tried to be brief in my reply..
