I upgraded both of my Windows 7 Professional computers to Windows 10 during the past few months. Last week, I had some time on my hands so I decided to upgrade the laptop, which was running Windows 7 Home Premium. It seemed to go fine but there were intermittent problems connecting mapped network drives.
I removed the mapped network drives, thinking that adding them anew would be a solution. Then I discovered that not all the computers see each other at all times. And what is really odd is that the two desktop computers seem to take turns displaying all the devices available on my home network. This issue manifests when browsing through file explorer, even though all three computers are in the same workgroup. It's maddening!
Even though I cannot see all the devices all the time using the file explorer, I can still map the drive using \\COMPUTER\sharename.
I put in a call to my paid pro support for the laptop, because it is relatively new. Dell abdicated responsibility but they conference called with me to Microsoft. That was a complete loss of hours of my life which will never be replenished. One day, they (Microsoft) tells me the support is free because Windows 10 is a new operating system. The next day, after being transferred hither and thither and being put on hold for extended periods of time over the course of an hour and a half, The rep came back and told us (Dell support was still on the call) that I would have to pay for support. I thanked Dell support for trying and told Microsoft support where to get off, and hung up.
During research, before calling anyone, I discovered that Windows 10, in its wisdom, creates a homegroup for each computer automatically. That's. Just. Wrong. It may be the cause of all the mayhem with Windows 10 networking. I think that I remember learning you couldn't simultaneously run a homegroup and a workgroup at the time I decided upon implementing a workgroup sort of network, way back in my XP days.
Anyway, this is my first actual post in the forum so I should probably stop ranting.
