Hit by this issue again, after a recent update to Windows 10, which I think disabled SMB1 silently.
Look, I know SMB1 is dated and has security issues and all, but we all have old equipment that we need to connect to and don't always have the means or resources to replacement them.
Quick reminder to self on how to enable SMB1:
- Launch PowerShell in Administrator mode
- Run "Enable-WindowsOptionalFeature -Online -FeatureName smb1protocol"
- Will be prompted to restarts Windows (sucks, I know..)
