I just upgraded to 10.5X and now I do not have the ability to locate an old PC I have on our home network for some file storage. The file was located in finder as a network device I believe and now there is nothing available. I as well can not locate the other PC's while using my Mac w/Leopard that are shared on this network. I have searched and can't even see where the network is located. The server unit is available to the other 3 PC's in the house but I can't find it with my Mac. I noticed that the Time Machine window has an on/off switch thing that makes it look for alternative drives to store info. When I turn this to on, it does locate anything either. Any ideas?
