Q: False "Server not found" error at startup

I have a new Mac Book Pro. When I start my computer, I get an error message about three times that says " Server Kevin's Computer not found" sewrver may not exist. Well as far as I know it does not exist. My wireless and everything works fine but I always ge this at startup and once in a while while I'm using the computer. I have looked everywhere for a reference to this server in my preferences and can't find any account of it. I did transfered all my data to it from an old Power MAc G5. Not sure if it is related to that. How can I get rid of this error. While it does not appear to be causing any issues, it does bug the **** out of me. Any help would be appreciated. MacBook Pro 2.7 GHz, OS 10.8.5.
