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

April 24, 2018what’s the fix for Win 10 home?
Aruna Lakmal
April 25, 2018Windows 10 home doesn’t have a gpedit.msc console. You have to install it manually as a third party tool. There are many links available in the internet. After installing the tool just follow the steps. Hope this will help you out. Thanks for the comment.

August 27, 2020does this fix need to be done to my pc or the pc im trying to conect to
Aruna Lakmal
August 28, 2020This should be in your local machine!
Andrew Fox
May 15, 2018Open Regedit, navigate here:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters
Double click on AllowInsecureGuestAuth and change it from 0 to 1. It should instantly start working without having to restart the computer or any Windows services/processes.

August 21, 2018Thank you! My new Surface Go was talking to my desktop computer beautifully last week, then this week the two refused to communicate. I tried all the usual troubleshooting steps and even created a new workgroup. My two older Surfaces and the desktop worked together and the Go would talk to the Surfaces, but I couldn’t get the Go and desktop working together.
Fortunately, this morning, I got the error message you wrote about, searched for info on it, and your instructions helped me fix the problem. Count me as another very relieved reader of this blog entry.

January 4, 2019Thank You Aruna. The perfect solution after days of frustration with Windows 10 build 1809. Even though the default setting was “not configured”, I did not have network access to my other workstations. Fixed immediately with the “enabled” setting.

January 15, 2019I LOVE YOU (no I’m not gay). Spent days updating, reconfiguring, resetting. Cause only one PC on the network was being stubborn and couldn’t browse said network. No idea why this was necessary but definitely solved my problem and in literally 2 mins. Thanks a million.

February 13, 2019Very helpful article. But I’m curious why this solution is needed? What triggers a logon as ‘guest insecure’? I’ve had no issues for years with this Server 2016/10Pro combo I’m using until last night! Patch Tuesday got me I guess.

July 23, 2019Cool! I’m using a Netgear C3000-100NAS modem (Comcast) and a LaCie housing, with a WD drive,using Win 10 Pro 64 ver. 1903, and couldn’t map the drive. A comment on the Netgear Community said I had to enable SMB 1.0, but that didn’t help – your tip got it to work – with just SMB Direct, not SMB 1.0 (which isn’t secure).
Aruna Lakmal
July 23, 2019Nice! Glad I could help you! 😊

Tom Ford
August 18, 2019Good information, and it gave me access – Thanks.. I have to admit when I first saw the term “Lanman,” I thought it only referred to the decades-old Novell product! Now that I have my USB 3.0 outboard drive working, the next step is upgrading my modem – mine has vague specs that hint at USB 2,0 High Speed, but really only has 2.0 standard; 12 mbps! That seems so slow now, but I remember upgrading hardware from the pre-standard 4 mbps to 10 mbps in 1984.

May 29, 2020I worked out why this no longer works in Windows 10 2004. The group policy editor does not change the correct value in the registry. Editing it manually worked
Navigate to: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters
Set: AllowInsecureGuestAuth to 1
