Why does my LAN keep saying I have access to another computer 30

The guest user of that machine didn't turn it on.

Problems with local security settings.

Method 1: 1, first open the computer firewall to confirm whether we have turned on the computer firewall, if it is on, we need to convert it to the off state.

2. Then open a folder in my computer and find the tool function in the toolbar.

3. Open the tool function and select the folder option.

4. After clicking on the folder option, a dialog box will pop up, find the view page, and turn off the function of using simple file sharing.

Method 2: 1: Press the win key and the r key at the same time to open the running interface. Then enter and click OK.

2. Then in the function bar on the right, find Windows Settings - Security Settings - Local Policies - User Rights Assignment. Then left-click User Entitlement Assignment.

3. Then find Deny access to this computer from the network on the new panel. Then left-click and double-click to open.

4. Finally, select guest in the pop-up dialog box, and then delete it, and that's it.

If you don't have permissions when accessing another computer, it could be due to the following reasons:

1.Wrong username or password: When accessing remotely, you need to enter the correct username and password for access.

If you don't have permissions, it's likely because you entered the wrong username or password. It is recommended to recheck that the username and password are correct.

2.Incorrect access permissions: When accessing remotely, you need to confirm that the other computer has been allowed access on the network.

Go to the control panel of the target computer, select the Shared Folder option, and then select Advanced Sharing Settings, where you can view and modify the sharing settings and permissions.

3.Firewall settings block access: When accessing another computer, if firewall software is installed on the target computer, and the firewall settings do not allow access from external computers, there will be no permissions.

It is recommended that you allow the relevant ports and programs in the firewall settings.

4.Network issues: If the network connection is unstable or not fast enough, it can also lead to a situation where access is not authorized. It is recommended to check whether the network connection is normal and optimize the network connection.

Overall, when accessing another computer, you need to make sure that there are no problems with the username, password, access settings, firewall, network connection, etc., to ensure smooth access.

First of all, make sure that the guest account is opened on your computer.

At the same time, press the win+r key to open the run input, open Group Policy --> Computer Configuration --> Windows Settings --> Security Settings --> Local Policy --> Security Options, and find the "Network Access --> Sharing and Security Mode of Local Accounts" set to "Guest Only"; Go to the bottom position, and "Account --> blank password is only allowed to log in to the console" is set to disabled. 3. Set the permissions of the shared folder (both the sharing tab and the security tab should be set), and allow the guest user to access it.

2. When sharing can access and open a file, it prompts that there is no permission.

The solution to this problem is actually very simple, open the folder you want to share, right-click "Properties" --Security --> Add -->eveyone (or enter a letter and click on the check name on the right).

Click OK > tick "Full Control" <

Then click on "Share".

Advanced Sharing "Permissions" – Full control over whether or not it has been checked.

Once the check is complete, click OK and you're good to go.
