The bold IP Address is your machine's IP. If you use DHCP (dynamic configuration), type IPCONFIG /RENEW on the command prompt. That should renew your IP. If you do manual IP, find out which machine is using the same IP address. Change it.

wheres the command prompt again

Click on the START button (lower left hand corner)

Click on RUN from the pop up window.

Type your Commands in the little window and there you go!

 

 

 BTW, I'm have the SAME IP address conflict Error show up on my LAN setup. I'm going to try the fix above and see what happens....
