How to eliminate Network setup and return to a standalone computer

This computer I inherited was originally a stand alone computer. Somewhere along the line it has taken on the characteristics of being a part of a network. The machine has a LAN hookup in the Network and Dial-up Connections window. This whole network thing is confusing and is causing me several problems.

Is there any way to undo all the network and LAN settings?

 

As an example: I have tried disabling the LAN connection, but when I do, in the Event Viewer I get an error that states the source as IPANTHLP with an event code of 31012.

This is just one example of some of the problems I've been having with this Network setup.

Please can anyone help?

I looked a little at the IPNATHLP and the 31012 and perhaps you are having problems with ICS.

I guess what I'm trying to do is to eliminate the LAN hookup settings because I am not on any network and I just want a stand-alone computer.

I noticed that the ultimate solution in the thread that FRED_G gave was to uninstall Sygate Personal Firewall and install Zone Alarm.

I don't want to do that.

I have a 3Com 3C918 Integrated Fast Ethernet Controller that was installed when I received this computer. It was set up on a LAN system.
I would like to eliminate the LAN setup. What is the consequences of uninstalling the Ethernet Controller? How do I eliminate the LAN setup so I can just use my dial up hookup to my modem?

Can anyone help?

 

I've already done that.

However, I did find the answer to one of my problems,

In the Internet Connection Sharing service in the Services menu I changed it from Automatic to Manual and it eliminated the Error in the Event Viewer.
