I just recently purchased my laptop so I am just learning. The message I got on the computer said, Another computer on this network has the same IP address as this computer. Contact your network administrator for help resolving this issue. More details are available in the Windows System event log. What does this mean and is this something important I need to fix. I would appreciate any help in this matter.

I see that message on my home network sometimes, and it's not critical.  If you have a home network, try powering off your router, waiting a few seconds, and powering it on.  If you're on a business network, consult with the network manager.

    I'm sorry: I don't know, either.
