Xp lan mutual access

1. Enable the Guest account

In many cases, for the security of the local system, the Guest account is disabled, so that you cannot access the shared resources of the machine. Therefore, you must enable the Guest account.

I will introduce Windows XP as an example. On the shared resource provider, go to "Control Panel> Management Tools", run the "Computer Management" tool, and then expand "Computer Management (local) → System Tools → local users and groups → users ", find the Guest account. If a Red Cross sign appears in the Guest account, it indicates that the account has been disabled. Right-click the account and remove the check mark of "account deactivated" in the guest Properties dialog box, click OK to enable the Guest account. This method is applicable to Windows 2000/XP/2003.

Tip: using a guest account to access Shared resources poses a major security risk. Of course, we can also create a specified account for each access user. First, create a new account on the shared resource provider, and then specify the access permission for this account. Next, create an account with the same user name and password in the client to access the shared resource. After you log on to the client using this account, you can access the shared resources allowed by this account. This method is relatively safe, but it is not suitable for large networks to create an account for each user in the network.

2. Modify the User Access Policy

Although the local guest account is enabled, the user still cannot access the shared resources provided by the local machine, because the Group Policy does not allow the Guest account to access the local machine from the network by default.

Click Start> run, and enter gpedit in the run box. MSC. In the Group Policy window, expand "Local Computer Policy → Computer Configuration → Windows Settings → Security Settings → local policy → user rights assignment" (figure 1 ), in the right column, find the "Deny access to this computer from the network" option, open it, delete the Guest account, and then open the "access to this computer from the network" option, add a guest account in the Properties window. In this way, you can use the Guest account to access the shared resources of the machine from the network. This method is applicable to Windows 2000/XP/2003.

3. correctly configure the network firewall
many machines have installed the network firewall. Improper configuration also prevents users from accessing shared resources on the local machine. In this case, the NetBIOS port required for sharing resources on the local machine must be opened. Taking Skynet firewall as an example, in the "custom IP rules" window, select the "allow LAN machines to use my shared resources" rule, and click "save, in this way, the NetBIOS port is opened.
.
4. reasonably set user access permissions
many machines on the network use the NTFS file system. Its ACL function (Access Control List) can control user access permissions, to access the shared resources of these machines, you must grant corresponding permissions. For example, if you use the Guest account to access the CPCW shared folder of the machine, right-click the shared directory, select "properties", switch to the "Security" tab, and add the Guest account to the user list, specify the access permission for the guest, at least grant the "read" and "list folder directories" permissions (figure 2 ). To allow multiple user accounts to access the shared directory, add the eeryone account and grant "read" and "list folders ?..
