Working principle of online neighbors

"Browse Service" is very important, many users have developed seriously dependent on "network neighbors".

After the user successfully logs in to the network, the next is usually access to network resources. In order to help users find network resources, Microsoft.com uses the mechanism called "browsing service" to complete network resource search and positioning. The customer's browsing process is as follows:

Add the server to the browse list by posting an announcement to the primary browser. The primary browser and the backup browser share server (domain) list. The client retrieves a list of computer from the primary browser. The client and backup browser contact to retrieve the server list. The client and server contact to retrieve the list of shared resources on the server.

On the network, in order to effectively locate network resources, the browsing service of the Microsoft Windows network must have specific "browsing servers" to participate and provide. The role of the browsing server is divided into "(Domain) Main Browsing Server," Backup Browse Server "," Potential Browsing Server ".

The browsing server is typically held by the first start-up computer, and then can be changed or handhailed by the election. Every 15 minutes, the main browser of each subnet declares themselves to other primary browsers on the subnet. Every 12 minutes, each domain master browser contacts WINS to obtain a list of all DomainName <1b> domains. Every 12 minutes, each primary browser (subnet) is connected to the domain master browser to update the browsing table. Every 12 minutes, each backup browser contacts its local primary browser to retrieve and update the browsing table. All server components (that is, the ability of the ability to share network resources) declare themselves to the primary browser in their local domain. A browser election occurs when the local subnet can't find a primary browser or an initial domain controller. The election is determined according to the operating system version number and identity. And most of the flow in this process is broadcast traffic. That's why WINS needs WINS in the multi-subsidy environment can use "network neighbors". Why is it trying to use the "network neighbor" as little as possible in the corporate network. Its work process determines that in a relatively large and dynamic change, it is destined to be unreliable and there are many problems and bring confusion. The browsing service does not have a direct control option, in addition to the Win9x can control whether the computer is a browsing server in the Network Properties - File and Print Shared Service Properties, must be done by modifying the registry. Here are some registry control parameters: (only test under Windows NT / Windows 2000) payment!

Hide specific computers in a network neighbor:.

Hidden your own computer

The above method is to hide a specific folder in the local area, if you want to hide your computer, please see:

Click Start → Run ", enter" CMD "in the Open" Run dialog box to open the command line window, enter "Net Config Server / Hidden: Yes", you can enter the bus, so that others can not Online neighbors directly see your computer, only access your computer by entering "// computer name" in the Explorer Address Bar.

However, the above method can only be valid for the current, and then re-run the command after restarting the system. If you want to keep your computer from the online neighbors, you can achieve the purpose by modifying the registry:

Open the registry editor, expand "HKEY_LOCAL_MACHINE /" in the left window

System / CurrentControlSet / Services / LanmanServer / parameters ", find DWORD type value in the right window to" 1 ", press" F5 "to refresh the registration table.

Of course, you can achieve this by turning off the "Server" service, but also loses the way to provide shared resources. You can modify the registry: / system / currentControlSet / Services / LanmanServer / parameters is established or modified: "hidden" = dword: 1/0 1 is hidden. You can also be accessed through the UNC path after hidden.

Another registry key for controlling whether it becomes a "browsing server": Win2000 computer, modify the registry: hkey_local_machine / system / currentcontrolset / services / browser / parameters "MaintainServerList" = reg_sz: Yes / no / auto "yes" as a browse Server, "No" does not act as "auto" automatic.

Win9X computer, control facilities - network - file and print shared service properties: Master browsing server: invalid / effective / automatic
