Ok everyone, I am "sorta" new to ubuntu and am now running a Ubuntu 12.04 LTS server.
I did a basic install of 12.04 lts 64-bit. After initial boot I logged in and ran 'sudo apt-get update'. After this i installed 'ubuntu-desktop' and 64-bit oracle jre. I have configured my static IP using the terminal. Everything was running great until I shutdown this morning to upgrade its RAM. The new ram is installed now and the server is running, but now network manager (ugh) is showing no wired connections. I have scoured the internet for a solution and have yet to find anything wrong with my settings.
I have the server KVM'd to my main desktop pc, and am writing this from that pc. Unfortunately, this makes it hard to copy paste from the server. I will provide any further information needed.

/etc/resolve.conf is appearently empty now.. must have been reset by network manager...
/etc/NetworkManager/NetworkManger.conf is also empty... i opened this to change it to:
since I read on ubuntu forums that I needed to do it in order to stop network manager from interfering with my manually configured terminal settings. I am not sure why it is an empty file...
One last thing for now, let me explain what I meant by "Everything was running great". I am running a minecraft server from this machine, it has been running and functioning properly until the shutdown today, and should continue to run after I fix this connection problem. By functioning properly I mean, This morning when i logged in to shut it down, my internet connection was still valid and working and i was still able to connect into the minecraft server from an external IP. I shutdown this morning, removed the RAM and doubled it, upon initial boot I am now stuck with this problem of no internet, yet every command I run appears to show the static is fine and I shouldn't have a problem. Thank you for your help and answers.
