| Test Environment Computer 1: Laptop wireless win7 x64 IP: 192.168.0.100
Computer 2: desktop computer network cable access WINXP SP3 IP: 192.168.0.101
Computer 3: Laptop wireless Internet access WINXP SP3 IP: 192.168.0.102 Network Environment Connect to the Internet gateway through a wireless router 192.168.0.1 Purpose Three computers share files, access each other, establish a LAN game Summary process: Sharing and access:
I. Necessity
1. An account with administrator permissions is required.
2. All computers accessing the network must be in the same IP segment, for example, 192.168.0.x (2 ≤ x ≤ 255)
3. All computers accessing the network must be in the same working group, for example, all computers in the workgroup.
4. the Guest account must be enabled for all computers connected to the network. The default account name is guest.
5. Disable any third-party firewall software or perform related settings (important ). Windows Firewall. If you have not disabled it, you also need to make some settings. Open Windows Firewall --- exception --- Select file and printer sharing --- OK --- save. On the General tab of the Windows XP system, remove the check box before the exceptions are not allowed.
6. The operating system of all computers connected to the network must have the correct permission settings (this is the key point)
7. XP refers to Windows XP Professional. Some of the methods described here are not applicable to Windows XP Home Edition.
8. Windows 7x64. Different Versions of win7 may be different. If you are using the Home Basic version, do not read it any more, because Home Basic does not provide the file sharing function ..
2. services that must be enabled
Right-click my computer or computer-Manage-services and applications, open the service, or use win + R to open the run --- enter services. MSC and press enter to open the service settings
Select [automatic] for the [Startup Type] of the following services, and ensure that [service status] is [started]
Server
Workstation
Computer Browser
DHCP Client
Remote Procedure Call
Remote Procedure Call (RPC) Locator
DNS Client
Function discovery resource publication
UPnP Device Host
SSDP Discovery
Tip/IP netbioshelper // This is very important. Even if other conditions are met, none of them will work.
III. Basic settings
A: XP system:
Download one-click Sharing of the xp lan. Click the settings and restart.
Windows XP file sharing: Right-click the folder to be shared, select [Share and security], and select share this folder on the network.
B: win7 system:
1. Network and sharing center --- click custom on the right of the network --- set the network type to Private Network
2. Sharing and discovery-enable network discovery, file sharing, and printer sharing. Password-protected sharing can be set to disabled.
3. printer sharing across operating systems involves driver issues. To avoid troubles, we recommend that you do not share printers across operating systems.
4. Access Policy Settings Run with win + R --- enter secpol. MSC and press enter to enable local security settings
Security Settings-Local Policies-Security Options
Account: A local account with a blank password can only log on to the console and is disabled.
This option is enabled by default. This is a key step because many computers do not have a password. If the account you are using does not have a password, you can only log on to the console, and you cannot access it through the network neighbor (XP) or network (Vista. So disable it here.
Network Access: Do not allow anonymous enumeration of SAM accounts and shares], set to disabled.
This option is disabled by default. Windows allows anonymous users to perform certain activities, such as enumerating domain accounts and network share names. This provides convenience and brings potential risks. Some versions of the system (such as the ghostxp computer company edition) are enabled for security purposes, but in this way, other computers on the LAN will not be able to view your shared content.
Network Access: The Sharing and security model of the Local Account, which is set to guest only.
This option is [classic] by default for computers that have joined the domain, and [Guest only] for independent computers by default. This is an auxiliary option for shared security. Computers in a small-scale LAN are mutually trusted and there is no illegal access. For convenience, we recommend that you use only the guest mode. In Classic mode, you can better define the access permissions for shared resources. This method can be used to prevent unauthorized access to shared resources for a larger LAN.
Security Settings-Local Policies-User Rights Assignment
Access this computer from the network: Check whether there is a local guest account, that is, guest. If not, add it.
Deny access to this computer from the network: Check whether the account name of the local guest exists. If yes, delete it. 5. win7 System File Sharing settings
Right-click the folder --- share --- Select the user you want to share with you --- click the Black Triangle arrow --- Select --- everyone from the drop-down menu (all users in this list ).
Note: folders shared before the above settings may need to be shared again before they can be accessed normally. For example, if you used the Classic mode to share the folder, an error occurs when you access the folder only in the guest mode, prompting you to have no permission. The solution is to cancel sharing and then share again.
PS: the firewall does not need to be closed. After all, the open-source sharing is not an open-source hacker! Security is still important. When sharing, security cannot be discarded.
You only need to set TCP ports 139 and 445, and UDP ports 137 and 138.
In addition, in the service, make sure that the TCP/IP netbioshelper service is automatic, but it does not mean that this function is enabled under wins. You must also get the TCP/IP settings of the NIC, enable the NetBIOS check on TCP/IP in wins to take effect! If you don't have the skills, it's hard to get through even if you have done all the work before! Even if it is occasionally connected, it is also temporary, and sometimes it is not connected, it is disconnected, disconnected! As long as this small hook is checked, it will be able to communicate steadily!
In addition
For people who have just played sharing, sometimes they cannot find the window to open and which button to press to see the other party. There is a big difference between win7 and XP.
In XP, everything has been set up. The network neighbor is entered, or the button on the left of my computer folder also contains the network neighbor. However, for a variety of complex reasons, not every XP computer can see the shared win7 computer here, the probability is only 50%, the reason is very complicated, if not, you can click "view Working Group Computer" on the left of the network neighbor. If the win7 side is set, it will be listed in "Working Group Computer" and then you can perform the operation.
In win7, many people will directly click the automatic discovery button of the home network, and there will be only one location, "shared computer not found". I have encountered many such things, don't work hard in this direction. This is a button for the home Intranet between win7 and win7. Even if both Windows 7 and Windows 7 may not be accessible, it is hard to work hard!
Click the "computer" folder on the desktop. The buttons on the left contain the word "network". Click this player directly, all the shared machines run out. Lan game online:
Summary: Prerequisites: Complete the above access and sharing settings to download the win7 IPX protocol 1. WINXP system settings Right click -- network neighbor -- Property -- local link -- Right click -- Property -- intermediate part of the local connection Property -- "Install", "Uninstall", and "attribute" buttons, after you click Install, you will see the "protocol" option and click "add".
