Viv, I don't think anyone questions you are having issues, but Glenn and I are also telling you we run windows 10 too and for the most part have not had issues. It's likely something specific to those machines. Have you checked the Event Viewer? Curious, what does "net view" tell you. I had a windows 10 where I ran the command and NOTHING came back and couldn't add a mapped/redirected printer. So despite it showing that nothing was there I did a net use lpt1 /del and not only did it remove something, now when I did a net view, it came back with results. YRMV.
