My daughter's group house has a network setup with a MAC (not sure but I think is Snow Leopard) and 2 PCs (XP). Everything had been fine until a about a week ago. Suddenly from the MAC, sometimes it can access the shared folders in the PC but most of the times it won't (showing the error msg in the thread title.) She says no changes has been made to any of the computers. Any idea? I know very little about MAC.
