This is gonna sound completely off the wall... I'm assuming that you're using the same ethernet cord. Have you tried a different port on the router?...

Here are the results from the last round of suggestions given:

Again, thanks for trying!

The route and resolv.conf have unexpected results. ie no routes and only a local nameserver.
Are you using a GUI with Ubuntu? If so, it may be simpler to click on the Network Manager icon in the system tray area and make sure you are actually connected to your network. If not, simply selecting it from the list should connect you. If not, try right clicking on it and selecting edit connections. From there you can make sure that your nic is configured as you expect.

Elija-Not sure if this is what you're looking for but when i do go to Network manager in the GUI, I see the IP, Subnet, Mac Address, etc. Everything looks "normal". All of the other settings appear to be the way they "should be". That is what started all of this, I thought it would be an easy fix via Network Manager. No such luck. Thanks for catching the error in the code!
I corrected the code and got the same results:
"chris@chris-desktop:~$ sudo /usr/sbin/dhcpd eth 0
[sudo] password for chris:
sudo: /usr/sbin/dhcpd: command not found
chris@chris-desktop:~$ whereis dhcpd
chris@chris-desktop:~$ sudo whereis dhcpd

I would recommend resetting the router to its default settings and see if you can pick up any settings that way. If it were me, I would run Wireshark before requesting an address through DHCP so that I can see the DORA process, or whatever might be happening. See picture below:

I am starting to wonder if it will be better to use a static configuration but rebooting the router could be worth a try. I've never encountered such a thing but maybe it already thinks a valid lease is assigned to the computer?

Once again I really appreciate all of the suggestions and apologize for the head scratching I have caused. However, i did manage to overlook one minute detail. Back to the suggestion to "change network cables". Well, I did. What I failed to notice was that regardless of which cable or port on the router I use, I do not get a green light on either end. I get an amber light (Not sure why I stated "green" before. Likely was assuming, not looking. It can't possibly e hardware, right?). I am almost convinced that I have a hardware problem. Likely centered around the NIC in the PC. Unfortunately it is on board. I will be replacing the machine with a new barebones unit and if all else fails, a fresh install of Ubuntu. Thanks again. Hopefully my next update will be from the new machine.

If these cables work on other computers, and the router ports connect properly, then it sounds like it is likely a hardware issue.
The best way that I can think to verify that is to use a LiveCD. Boot up to a Live session, and see if you have connectivity.
