Blocked Access Shared Folder Organization Security Policies

Blocked Access Shared Folder Organization Security Policies - Hello friends, in this post, I will share my experience in dealing with an issue on a Windows Server 2019 that cannot access a shared folder within the internal network.

Issue

The specific error message is "You Can't Access This Shared Folder Because Your Organization's Security Policies Block".

You Can't Access This Shared Folder Because Your Organization's Security Policies Block

Cause

The causes of the error message "You Can't Access This Shared Folder Because Your Organization's Security Policies Block" are security policies implemented by the organization or network administrator. Some possible causes include

1. Group policy restrictions

The network administrator may have applied group policies that restrict user access to the shared folder. These policies could involve limitations at the user level, user group level, or specific computers.

2. Firewalls or other barriers

Security systems such as firewalls or other security software may be configured to block access to the shared folder. This can be done to protect sensitive data or reduce the risk of attacks from the internal network.

3. Incorrect permission configuration

There is a possibility that the permissions to access the shared folder are not properly configured. Incorrect or inadequate permissions can result in this error message.

Resolution

After I checked several solutions and tried them out, I managed to find the appropriate method, which is to modify the parameters within the regedit.

Step 1: Open Parameter Regedit

Windows + R 
Open: regedit - ok - yes
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters

AllowInsecureGuestAuth

Step 2: Change Value

Change Value data from 0 to 1 - ok

AllowInsecureGuestAuth 1

Trying

After following all the steps mentioned above, you can now try accessing the shared folder again, which was previously inaccessible.

Accessing the Shared Folder

If you still can't succeed with this method, there may be other possible causes that you should recheck. If you can resolve the problem using the same solution as mentioned above, congratulations on successfully resolving the issue caused by the error message "You Can't Access This Shared Folder Because Your Organization's Security Policies Block."
