This has been confirmed to work on Windows 10 Enterprise and Windows 10 Pro both versioned as 1803.

Tons of posts related to Windows 10 and SMB as the root cause of the inability to connect to unRaid that were fruitless so I'm recording this easy fix for my future self. If you cannot access your unRaid shares via DNS name ( \\tower ) and/or via ip address ( \\192.168.x.y ) then try this. These steps do NOT require you to enable SMB 1.0; which is insecure. Directions: Press the Windows key + R shortcut to open the Run command window. Type in gpedit.msc and press OK. Select Computer Configuration -> Administrative Templates -> Network -> Lanman Workstation and double click Enable insecure guest logons and set it to Enabled. Now attempt to access \\tower Related Errors: Windows cannot access \\tower Windows cannot access \\192.168.1.102 You can't access this shared folder because your organization's security policies block unauthenticated guest access. These policies help protect your PC from unsafe or malicious devices on the network.
