What you say makes very good sense. As I said in an earlier post I fail to see any utility in either Libraries or Homegroups. The problem I have right now is that, although all three computers are members of the Workgroup, CPU4 and CPU8 are prompted for a network password when trying to access CPU7. Everything else in the network seems to work as expected. I have no idea why CPU7 is special in some way. I do not know what the Network Password might be, or how to discover it. If you could shed any light on that question, you would do me a great service, not to mention generations as yet unborn who will likely be struggling with Microsoft Networking twenty years from now.
