This happend to me also years ago when the guy came from the cable company to install our first modem for the cable internet... I hated it!!
I called a friend of mine who is an IT person and he said to goto control panel/Network and remove what the guy put on "CLIENT FOR MICRSOFT NETWORKS"
I did and im thankful!! (Im on Win98se (My favourite OS))
Caroline: I hope what TAF posted worked for you
