How to determine the correct installation of the network adapter in the win 2003 system?

After using the software for a period of time, many users will ask such a question, ask: The same internal LAN, win2003 network neighbors only see themselves? This is Not because your network adapter is not installed, in fact, the opposite is true.

A: In the "My Network Places", I only see myself, indicating that the installation of the network adapter is correct.

A) But you can't see other machines in the network. If this happens, first confirm whether the network cable is plugged in, and whether the related network devices HUB and switches are working properly. A number of users have encountered such a situation, no matter how toss a computer can not get on the network, and finally found that the network cable between the switch and the computer network card is not connected. In the past, in the case of such problems, you should first consider from a simple point of view, in addition to confirming that the network cable has been plugged in, but also to confirm whether the network cable is working properly, using parallel lines or cross lines. Parallel lines are used to connect different types of devices, such as network card ——HUB/switch; parallel lines are used to connect similar devices, such as HUB/switch & mdash; — HUB/switch (hub/switch with cascaded port) When it comes to), network card - network card.

B) If everything is ok, still can't connect to the network, it depends on whether the computer belonging to the same working group has a duplicate name.

C) If both conditions are normal, it depends on whether the agreement is a problem. In general, LAN uses TCP/IP protocol (this is WINDOWS default network communication protocol, as long as your network card is installed successfully, it will automatically join) is enough. First, confirm that the local TCP/IP configuration is correct at the Start & rdquo;-“Run& quoquo; command ping 127.0.0.1. Someone used this ping command to determine if the network card is faulty, but this is not true, because ICMP is considered to be an integral part of the IP layer. When the local address is pinged to the IP layer, it is shorted and no network card driver is called. The program, so it is impossible to judge whether the network card is faulty, and does not use a higher layer protocol (such as TCP or UDP); in fact, if the ping command returns a normal result, only the local TCP/IP protocol is correctly installed. Details on using the ping command to detect a LAN failure will be described in detail later.

D) ping another host in the LAN, if the returned result is correct, but still can not see it in the network neighborhood, indicating that the other computer does not open the "file and printer sharing" service; of course If you want others to see you, you must also open “File and Printer Sharing", otherwise others will not see you.

E) All settings of TCP/IP use the default value of WINDOWS, so in a LAN with full service (DNS, DHCP, WINS service), you can enjoy the benefits brought by the LAN. However, in a peer-to-peer network with only a few machines, there may be no host to provide the required services. TCP/IP needs to be specially set up. You must specify the IP addresses of each computer and put them on the same network segment. Two identical IP addresses are specified; each computer gateway is designated as the same computer on the LAN; DNS is specified; bind files and printer shares and Microsoft network clients; other settings retain the default values ​​for WINDOWS. Also add “Microsoft Web Client" and <;File and Printer Sharing on the Microsoft Network". In the peer-to-peer network, it should be based on the principle of “Ningduo no shortage”, and other agreements can also be installed. Common ones are: IPX/SPX compatible protocol, NetBEUI network protocol; finally set the basic network login mode to “Microsoft Network Client”.

Under normal circumstances, run the “Network Connection Wizard” and open the guest account. Each machine runs once~ Share files and print services must be selected~

So things don't want to be seen on the surface. Sometimes you think that abnormal imagination is the right thing, so everyone should accumulate more knowledge, so that they can understand when there is a problem.
