Recently, my father tried to tempoary connect ou computer to another. Even if it didnt work out on the other end, it seems it did on this one. Since now, when I try to close my computer I (sometimes) get an error message telling me that Some computer is connected to mine... Since I know its not my other computer (its not even plugged in right now). I was wondering how am I supposed to remove the network settings so that people can no longer connect to my computer

I am using that pice of crap called WinME.
