I have classes in the school computer room. How can I send information to the teacher's computer through the Internet?

Three methods of sending information to each other in LAN

Many people may have had this experience: when using a computer in the computer room, a message window suddenly popped up on the screen, which scared you! These message windows are usually sent by the computer room or the network manager of the company, and their purpose is to announce some important matters to users, such as announcing the end of the course or the upcoming closure of the computer room. Do you want to know how to publish these messages? This article can tell you! In fact, it is not difficult to convey such information. You can use the following three methods:

First, use Microsoft Management Console (MMC) to send messages.

There is a Microsoft Management Console (MMC) in Windows XP that allows you to send messages to every computer in your workgroup or domain. The message you send will be displayed on the other party's desktop so that the network administrator can broadcast the message to all users. The method of sending messages using MMC is as follows:

In Windows XP, click Start/Settings/Control Panel, click Administrative Tools in Control Panel, and then double-click Computer Management. In the computer management window, click the Action menu and select All Tasks/Send Console Message; Then in the pop-up window, enter the message to be sent, press the "Add" button, select the computer to receive the message, and finally press the "Send" button. Messages you send in the future will be displayed in the Messenger service box on the other party's desktop.

If the recipient is not in the recipient list, you can click the Add button to create a new computer. The Select Computer dialog box will pop up, then select the workgroup or domain you want to visit, and click the corresponding calculation name to add them to the recipient list.

Tip: You can access the Microsoft Management Console (MMC) and send messages through MMC only if you have administrative rights on the local computer. If the current account does not have administrative rights, please log in to the Windows system again with an administrator account. The above skills have been successfully tested on Windows XP Professional.

Second, use the net send command to send messages.

Windows XP/2000 provides the command net send to send network messages. You can also use this command to send messages to LAN/WAN. Be careful not to cross the network segment! The format of this command is: net sends the computer name /IP address "message content".

For example, to send a message "The server will shut down in 5 minutes" to a computer with IP address192.1,you can do the following: click Start/Programs/Accessories/Command Prompt and type the following command:

Net send192.192.192.1"The server will be shut down after work in 5 minutes."

Please wait a moment. On the desktop of 192. 192. 1, a window titled "Messenger Service" will pop up, which shows the message you sent.

Tip: If the other party closes the Messenger service, this message will not be displayed. If you don't want to receive this kind of message, you can also click Start/Settings/Control Panel/Administrative Tools/Services to turn off the "Messenger Service" in the service; If you want to start the messenger service, you can do it in the service. Of course, you can also use the following command to start or stop the messenger service:

Net stopMessenger stops the messenger service;

Net startMessenger starts the messenger service.

Third, use the software net send GUI to send messages.

The above method of sending messages actually uses the Messenger service of Microsoft Windows. It is not easy to convey information with blunt instructions. Besides remembering the instructions, you have to choose the scope of information broadcasting, which is a bit awkward to use. If for the company's MIS personnel, sometimes the object to be broadcast may only be a certain department or floor, then it is even more difficult to choose the scope. At this time, the Net Send GUI software comes in handy, and it is easy to send messages with it.

Net Send GUI is a free gadget, which allows you to send messages on the graphical interface, changing the inconvenience of sending messages with commands in the past and making it easier for you to operate. You can use the Net Send GUI to specify the scope and messages to be broadcast, or even specify the scope to broadcast only a certain domain.

Net Send GUI is a portable application, which needs no installation and only has one screen after running. If you want to broadcast messages to all computers in the current domain, you can select "This Domin"; If you want to specify a specific domain for broadcasting, please check "Specific Domin", and then enter the domain name and the information to be broadcast in the message in the "Domin Name" column.

If you want to send a message to a computer with an IP address, do not check "this Domin" and "specific Domin", enter the IP of the computer in the "Send message to" column, then enter the information to be broadcast in the message, and then press the "Send" button to send it.

In addition, the Net Send GUI is not only a message broadcaster, but also provides a Ping function. Clicking the "Ping" button can help the network administrator to confirm which computers are not turned off, which is convenient for the network administrator to manage.
