I have three windows computers. Device 1 - is a Lenovo desktop Device 2 is a Dell laptop Device 3 is a HP laptop. Device 1 can see all three devices on the network and can access files on Device 2 and Device 3 drives. Device 2 can see all three devices on the network and can access files on Device 1 and Device 3 drives. Device 3 can see all three devices on the network and can only access files on Device 2 drives but can NOT access files on Device 1 Drive. Here is the troubleshooting I have performed 1 - Check Sharing Permissions: I checked sharing permissions an all devices have drives/folders shared with appropriate permissions. 2 - Security permissions: All devices have security features turned on so everyone can have full control. 3 - Network Credentials: I have checked network credentials used on device 3 for device 1 and the credential are correct (my microsoft email and password). Device 1 does not use a local account. 4 - Enable SMB1.0/CIFS File Sharing support: I have enabled SMB1.0/CIFS file sharing support and ensured it is on for each device When on Device 3 and trying to access Device 1 drives i get the following message. Enter network credentials to connect to: Device 1 and it shows my email and wants me to enter a password. The password i enter is my Microsoft account password. When I enter my password it says the username or password is incorrect. Please advise as to what do I need to do to get Device 3 to access Device 1 folders?

Thanks First of all, create a restore point > Start Menu > Settings > System > About > System Protection > Create You will perform the following procedure on computer 1. Restart the PC, remembering to grant permissions to everyone on the shared directory to perform the test. Press Win + R, type regedit, and press Enter to open the Registry Editor. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters. If the AllowInsecureGuestAuth entry does not exist, right-click and select New > DWORD (32-bit) Value, and name it AllowInsecureGuestAuth. Set the value of AllowInsecureGuestAuth to 1. Close the Registry Editor and restart your computer.

Then, grant the account permissions to access the folder and see if the problem occurs there. Thanks 0 votes If you're unsure, try creating a local account and see if the error persists.

Sorry if these are dumb questions... THanks 0 votes Thanks Ivan, i will read up on how to create a local account. If I were to do that would it mean my Device 2 would not work with Device 1?

To create a local account: In the Settings app on your Windows device, select Accounts > Other users > Under Add another user, select Add account > select the option that I don't have this person's sign-in information > Add a user without a Microsoft account. Set the account type as administrator. As a precaution, create a system restore point before doing anything.

All of them?, then what, try to connect using the local account name and password between any pair? What if a VPN is active on one of the systems, or all? As it is it is nice to see an answer that worked for someone but not well explained. 0 votes Could the person who got this to work, DW, or Ivan B., please add: which machine gets the local account?
