Dear Members, I have 6 Win 10 desktops and laptops networked via cable and wireless at home. All working well seeing each other and being able to access files/folders on each. My issue is that I added a very old Intel Pentium, Win XP desktop machine, and I am unable to see the XP asset, on any of the Win 10 machines. Surprisingly, from the new additional Win XP desktop machine, I can see all of the active Win 10 machines, but I cannot access files/folders. I get the error message that the network computer is unavailable and I do not have the necessary permission for access...go see my administrator. Any advice? My gut feeling is that the problem is very basic, but I am missing something. My expectation is that the XP desktop should be able to join join my existing Win 10 home network. Thanks for any thoughts.
