With all the network share changes to the latest versions of Windows 10 (1909) and now the BS with 2004 breaking network drivers as well as most chipset drivers and maintenance software.
Windows 10 2004 is like a new, untested OS.
After 3 weeks of formatting and reinstalling, and messing around with the Services, etc. Then a Microsoft tech telling me I must use their online Cloud for the network. I was like, these
computers are for research and don't go online because of sensitive data. He basically told me to try Windows 7 or 8.1 as they still support the easy file share (HomeGroup) protocol for offline systems.
So here we go, Downloading and putting Windows 7 on my server again. It makes life so much easier for Networking offline.
Thanks "The RAIN" for putting out such a great package.
