I've been tearing my hair out trying to connect to an SMB share and I keep getting "Unexpected Network Error" and "Error 0x80004005". I've tried enabling SMBv1 in Windows Features, and I've tried ensuring that sharing is enabled on the network. It is a Linux-based NAS server that is kinda old but I don't have the details on it. I can connect to it via my MBP (macOS Mojave), so this is confusing me.
Does anyone know how I can connect to this server?

Other systems in our org needed these changes:
RequireSecureNegotiateand set it to
Then everything worked.
