You can’t access this shared folder because your organization’s security policies block unauthenticated guest access

I ran in to this while I was trying to access My Lacie NAS drive from my Windows 10 computer. NAS was directly connected to the network and no access permissions required to access the shared folders. I have set permissions according to the user groups. So anyone who got the access permissions can access the relevant folders and if users don’t have the permissions folders will not be displaying in the explorer.

So I tried to connect this drive as a Network file share to my laptop and I was prompted with this error message on my screen. So I thought to share this post in my blog so anyone who has the same issue able to find this in the internet easily.

This is the prompted error message

So I found that this access is blocking from the local group policy and I opened the Run window (Win + R) and typed gpedit.msc to open the Local Group Policy Editor.

Navigated to Computer Configuration -> Administrative Templates -> Network -> Lanman Workstation and selected the Enable insecure guest logons as shown in the below screenshot

By default it was disabled and I have enabled the policy

Click OK to apply the policy and tried to access the shared network drive, I was able to access My Lacie NAS drive from the windows explorer
