Solution 1: Installing SBMV1
This error mostly occurs with devices that are not recent and have a different sharing protocol installed i.e. SMBV1. The new windows update has this uninstalled by default which is why you are experiencing the problem due to the vulnerability of the past. We can easily add it using windows features and check if the problem gets solved.
Solution 2: Editing Group Policy for insecure logins
Another workaround is to edit the group policy for insecure logins. Do note that the group policy editor is a powerful tool and changing keys which you don’t know about can make your computer unusable. Computer Configuration > Administrative Templates > Network > Lanman Workstation
Solution 3: Installing Client for Microsoft Networks
Another workaround is to ensure that the client for Microsoft Networks is installed and running on your computer. Before that installing, we will reset the Winsock context.
Solution 4: Changing HomeGroup Settings
In this workaround, we will try changing the homegroup settings from the client PC (the PC which is sharing the file with others) with a few amendments in the properties of the file being shared.
If it is not present, click on Add, select Advanced, and click on “Find Now” present at the right side of the screen. Now Windows will search for all the users available and list them at the bottom of the screen. Highlight “Everyone” and press Ok. Everyone will now be available in the permissions block. Make sure that it is activated. Press Apply to save changes and exit. Now try accessing the file from another computer and check if our method is successful.
Solution 5: Making sure Public Sharing is turned on
Another reason why your folder isn’t being shared over the network is that your public sharing might be turned off. Even if you turned it on previously before the update, check again as many configurations get reset.
Sometimes a restart is required to make sure that all the changes are implemented.
Solution 6: Executing PowerShell Command
In some cases, executing a simple command in an elevated PowerShell seems to do the trick. Therefore, in this step, we will be doing that. For that:
