Windows cannot open this file..

Everytime I log on, I get a popup that says "Windows cannot open this file : TFTP 1256" and the option to look for the program to open it.

Im using Windows XP Pro ( no SP yet). I was just curious what this file was, I havent installed any virus programs yet so I am kind of concerned.

Thanks,

did a search in google and the best thing I could find is that it has something to do with networking

I wonder if it has to do with the fact that i have my onboard lan enabled but not in use. Ill go try to disable it in BIOS

Thanks!
