Urgent need for network experts LAN mutual access problem 50

The first level of LAN mutual access:

Local Security Policy - Security Options - Accounts: Local accounts with blank passwords are only allowed to log in to the console. The system default is: Enabled.

Login failed: User account restrictions .........This is due to a security policy in the XP system that prevents others from accessing your computer when you have an empty password. If you don't think it matters, you should set it to:

Disabled. The second level of LAN mutual access:

Control Panel - Firewall - Exceptions - File and Printer Sharing. System default: Do not select this option.

Hehe, it's really infuriating. This is because XP also has a level, which is the firewall, which must be allowed by the firewall.

Local accounts with blank passwords are only allowed to log in to the console. The default value is changed to: Deactivated.

Can't access, do you guys open it for guest users?

The username may not be the same for each computer. A guest is a guest user. needs to be opened. Control panel. Account management. I found it. The Working Group would also have to join. So that it can be accessed. Hope it helps.

Not all of them are logged in with the administrator user, if they are, you need to enter the password, and you can use another user instead. But remember to turn on the guest users, and never need a password to access each other.

The Vista system is more secure than XP, which is why it requires a username and password. It would be nice to change the XP system.

If you do not want to enter a password to access, please set the password of the current user of Vista to the same password of the same username on the shared machine. You can access it directly.
