Local area network sharing and Internet skills four

Question 1: There are five computers in the office, are connected to the Internet through the sharing of ADSL broadband, in these computers when the Internet, found that some pages can not be opened, but through dial-up or dedicated line to the Internet, found that these pages are open, do not know why this phenomenon occurs?

Answer: This phenomenon, it is possible ADSL broadband Internet access, the use of the PPPoE protocol "provoke" the curse. Because the PPPoE protocol has certain limits on the amount of data that is sent or received each time it is exceeded (the maximum transmission unit can only be 1500), it may cause network access to be abnormal. To avoid sending or accepting packets that are too large, you must limit the maximum number of transmission units for TCP packets.

For example, if the LAN workstation uses the Win2000 system, then you can expand the registry branch in turn Hkey_local_machine\system\currentcontrolset\services\tcpip\parameters\ Interfaces (as shown in Figure 1), then, in the right child window of the corresponding "interfaces" primary key, right-click the blank area, execute the new/double-byte Value command in the shortcut menu, and set the new key value name to "MTU" and set the value to "1490" (in decimal). If you pass the above settings, you can not access the page correctly, you may wish to modify the "MTU", the value of the change to a smaller number of try.

Issue 2: When sharing the Internet over a broadband router, we sometimes need to enable the UPnP function of the router (Universal Plug and Play) in order to get a faster share transfer speed, how can I properly enable this function under WinXP?

Answer: At present, the new broadband routers have good support for UPnP, but in the default settings, the WinXP system does not support UPnP, so we often need to manually install the feature components. Of course, before you install, first, enter the IP address of the router in the address bar of IE, and go to its Web Administration page, find the UPnP option of the router in the page, see if the option has been "activated", and if not, set it to "enable". Next, open the Add or Remove Programs interface of the WinXP system, continue to click the Add/Remove Windows Components button, and then select the Network Services option, click the Verbose button, and then select the Universal Plug and Play item. After restarting the computer system, open the Network Neighborhood window to see if there is a "shadow" of the broadband router, and if so, it indicates that WinXP has enabled the UPnP function correctly.

Problem 3: The local area network in the unit is through the 10M broadband fiber access to the Internet, and now want to use BitTorrent and friends to share the audio and video files in the LAN workstation, do not know how to make the share transfer speed faster?

Answer: Considering BitTorrent at work, always in a multithreaded transmission state, we should think of ways to increase disk cache capacity, as far as possible to avoid BitTorrent "dual-use" to frequent access to the hard disk, so as to ensure that the shared transmission always at full speed.

To increase the disk cache capacity, you can first open the registry editing interface, and then position the mouse over the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory On the Management branch, check to see if there is a "iopagelocklimit" key in the right child window of Memory Management (as shown in Figure 2), and if not, click New/Double-byte value in the right-click menu to create it. and set its numeric value to "8000" or higher (in hexadecimal), and then click OK and reboot the system to make the settings effective.

Question 4: Between workstations in a local area network, it is common to transfer shared files to one another; however, many people, when transferring shared files, often open the shared folder of the other workstation, and then copy the local shared files to the other shared folder, if the other shared folder "hiding" the number of layers, This method is undoubtedly very cumbersome. So is there a faster way to share a transmission, and if so, how?

Answer: Yes, you can use the "Send to" feature in the Windows system to achieve faster sharing of file sending operations. The following author takes the Win2000 system as an example, to introduce the specific implementation steps: First open the Explorer window, click the Tools/Folders option in the window, go to the View tab page, select the "Show All Files and folders" option, and then click the "OK" button, " The SendTo folder is "visible" (by default, the folder is hidden), then expand Documents and Settings, user name, SendTo folder, and then open the Network Places window to share the folder's shortcut icon. Drag directly into the SendTo folder window. When you want to send a local file to the other shared folder quickly, you can right-click on the target file, perform the Send To command from the pop-up shortcut menu, and select the shortcut icon for the other shared folder in the subsequent Downlevel menu, so your target file can be quickly transferred to the other computer.
