A password is required to access a LAN computer, and a password is required for LAN connection

This is a different version of the system, but it doesn't matter. As long as you enter the other party's username and password, you can access it, and you can use the administrator to manage the account, and you can enter without a password, but it also depends on whether someone else's administrator account has a password

If it is Windows XP Professional, it is the name and password of computer B to log in to the system. If not, you can also access it with an Adiministor account and password. That is, the password set when the system is first installed in 2000 professional.

The computer system you want to access should be Windows 2000 ProfessionalTo access Windows 2000 Professional, you must use the Adiministor account and password of computer B. The Adimistor password is the password you set when you first installed Windows 2000 Professional (maybe you can use Adimistor to directly connect the Enter key to enter the computer without setting a password).

You try.

Make the following settings on a machine that cannot be accessed.

Control Panel--- Computer Management--- Local Security Policies---Local Policies--- User Rights Assignment--- There is an item on the left side of the computer deny access from the network, double-click to delete all users in it, OK

Guest account not opened? Or set up password access.

With the increase of the number of computers in the network, the data that needs to be broadcast in the LAN will increase dramatically, which will seriously affect the work efficiency of the network. Here's what I've compiled for you about how to remove the password required for LAN connection, let's take a look!

LAN connections need to be deciphered

Let's troubleshoot the issue by following the steps below.

2Question 1: Is the guest account disabled? If you disable it, you can change it to enable, if it has been changed to enable, look directly at question 2.

The method is: we right-click on "My Computer" and "Manage".

3. In the pop-up dialog box, select "Local Users and Groups", "Users", and "Guest".

4. Let's right-click the "guest" attribute and remove the checkmark in front of "account disabled" in the pop-up dialog box.

5. Question 2: If the guest is enabled, the following icon pops up when we access the computer.

Login failed: The user was not granted the request login type on the computer

6 The problem is that we didn't add the guest user to the list of allowed access on the computer.

Here's how: Let's select "Control Panel"."Management tools"Local Security Policy

7 We select "Local Policy", "User Rights Assignment", "Access this computer from the network".

8. Add the guest user in the pop-up dialog box of "Access this computer from the network" (the method is: add a user or group Advanced Find guest immediately OK. )

9 We can see that guest has been added to the allowlist.

10. We go back to the "User Rights Assignment" interface and select "Deny access to this computer from the network".

11In the dialog box that appears, select Guest.

At this point, we can access the computer in the LAN through the guest user.

End is accessed with Windows authentication.

If we don't want to open our guest user and still want to access the other party's computer, we need to access it through Windows authentication (i.e., log in with a username and password).

The username here is: Boot of the computer being accessed.

The password here is: the boot password of the computer being accessed.

Therefore, we need to know the boot and password of the accessed computer in advance. If you don't know, you can only access it through your guest account.

If the boot password of the other party's computer is empty, we click "OK" after entering, and the following prompt will pop up.

Solution: Let's open "Control Panel" "Administrative Tools" "Local Security Policies" "Local Policies" "Security Options" "Account: Local accounts with empty passwords are only allowed to be accessed by the console".

Let's double-click on the option to change it to "Disabled".

That is, you can log in to the computer with an empty password.
