I'm just curious as to how the problem arose in the first place
There is an article here
which explains a little about automatic IP addressing.
It was very unlikely anything you did, it occurs when your computer (the client) cannot obtain information from a DHCP server (your ISP provider) for whatever reason - could be the DHCP server was not available at that particular time.
Usually a reboot will resolve it.
Ok. if everything is now fine...Good News!
- Your system now appears to be clean
Now for some clean up and "housekeeping"
A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset System Restore points:
