Win XP LAN settings and inaccessible solutions

I believe that many people have the same experience as the author. The network configuration of WIN XP is exactly the same as that of WIN 2000, but there is still a situation that cannot be accessed at all. I think this is mainly because of XP security. The setting is different from 2000. In response to this problem, the author checked some information on the Internet and tested various common solutions provided online. Now I will introduce it to everyone, I hope that I can help the users who have encountered this problem, and please continue to give pointers to the experts. .
First of all, physical connections and other issues are not considered here, only strategic issues are discussed. In addition, please install the corresponding protocol and set the IP address correctly, and try to set the computer in a working group and have the IP address of the same network segment.
Secondly, there are many descriptions of the problems on the Internet, so I won't repeat them here. When sharing and access problems, please consider the following steps:

1. Check the guest account does not open the guest account is turned down
XP by default, so some other people to be able to browse your computer, Enable the guest account. At the same time, for security, please set a password or corresponding permission for the guest. Of course, you can also set a username and password for each machine so that computers can access each other.

2. Check whether the refusal Guest user access to the network machine
When you open a guest account but still can not visit, please check the settings to deny guest access to the computer from the network, because the default XP The guest is not allowed to log in from the network, so even if the guest is opened, it cannot be accessed. Unlock the Guest account when the system Guest user is enabled, click “Start →Run”, in the "Run” dialog box, enter “GPEDIT.MSC” to open the Group Policy Editor, in turn Select “Computer Configuration & Rarr; Windows Settings & Rarr; Security Settings & Rarr; Local Policies & Rarr; User Rights Assignment & rdquo;, double-click "Reject access to this computer from the network" strategy, delete the "GUEST" account. In this way, other users can use the Guest account to access the computer using Windows XP system through the network.

3. to change the network access mode
XP default is to log all users from the network are handled by the guest account, so even if permission from the network administrator to log only have guests, if not met In the case of access, try changing the access mode of the network. Open the Group Policy Editor, select “Computer Configuration →Windows Settings →Security Settings→Local Policies→Security Options", double-click "Network Access: Local Account Sharing and Security Mode” Policy, Default Set “only guest & mdash; local user since guest authentication & rdquo;, change to “ classic: local users authenticate with their own & rdquo;.
So even if you don't open the guest, you can log in to the computer you want to access by entering your local account and password. The local account and password are the account and password already in the computer you want to access. If you need an account and password to access the network, you can log in by entering the account and password already on the computer you want to access.
If you don't change the access mode, you may not be able to enter the username and password. //computername/guest is grayed out. Even if the password is empty, you can't make sure to log in without opening the guest. Change to the classic mode, at least as long as the case of not opening the guest account in 2000, you can enter the user name and password to log in to the computer you want to enter. Maybe you will also encounter a special situation, please see the next one.

4. One notable problem
we may encounter another problem, that is, when the user's password is empty, even if you do all of the above changes still can not log in, access Still will be rejected. This is because, in the system "Security Options", there is a "Account: Local account with a blank password is only allowed to log in to the console" policy is enabled by default, according to the principle of rejecting priority in Windows XP security policy, password An empty user will be banned when accessing a computer using Windows XP over the network. We just need to disable this strategy to solve the problem. In the security options, find the "local account with a blank password and only allow the console login" item, disable it, otherwise you will not be able to log in even if you open the guest and change to the classic mode. After the above changes are basically accessible, you can try to choose a method that suits you. Here are some additional questions you might encounter.
