Recently rebuilt my Windows 10 (1909) desktop and I’ve been unable to get to my UNRAID shares. It’s been driving me crazy as nothing with my servers or network has changed. I can still manage UNRAID with the root and password I’ve always used so it has to be something with my freshly imaged computer.
Turns out Microsoft has made some adjustments to network shares. (I’m using Win10 Pro/Enterprise. There is one little group policy object we need to change.
Open a command prompt on your windows machine and type in: gpedit.msc then enter.
What Policy Needs To be Changed
Computer Configuration > Administrative Templates > Network > Lanman Workstation > Enable insecure guest logins.
Edit the policy and enable it.
Your shares should be accessible again! No need to reboot or log off.
