My W2000 networked system at work has all of the desktop icons covered (not replaced) with another icon. The overlaid icon shows a hammer and screwdriver on a directory symbol. What does this mean? This happened when a coworker tried to play a cd on my system through our network. the performance of the system has not changed. Our IT person does not know anything about it. My web searches come up blank and Microsoft oriented message boards have not given any good answers. I made the problem go away by reinstalling the OS. I still would like to find out what these icons represented.
