The high score is rewarded, the LAN connection is not available, and DHCP does not assign IPs

This happens a lot as well, just plug in the socket on the switch a few more times!

I don't know the specifics, hehe.

Summary. As far as the description, 1If the IP address entered is not used, then there will be no IP conflict. After the IP address is used, DHCP can no longer assign the used IP address.

2.If the entered IP address has been assigned by DHCP, a conflict will be displayed.

DHCP automatic IP assignment is enabled in the LAN, and someone manually enters the IP and does not automatically obtain it, so there will be no IP address conflict!

As far as the description, 1If the IP address entered is not used, then there will be no IP conflict. After the IP address is used, DHCP can no longer assign the used IP address. 2.If the entered IP address has been assigned by DHCP, a conflict will be displayed.

Thank you. So, there are no IP address conflicts.

You're welcome, if you have any doubts, you continue to ask.

Is this question so complicated?

Since it doesn't work automatically, you can fill in one manually first, see if you can ping the same external network and intranet, if you can, it's a matter of service, check the configuration file. If not, there is a problem with the client, most likely on the network card or driver. Such a simple question I don't understand why it makes your discussion so complicated ...

And the guy upstairs, DHCP is on by default.

Start running the input: Enter, find the DHCP service - set the drop-down to select automatic-click and then click to start! Reboot!

You can directly modify the MAC address of your network card.。。。

I'll answer that question! XP system, right-click on my computer --Properties --Manage --Services --Find DHCP Service --Enable --OK.

Uninstall the network card, reinstall it, try the old version or the latest version, is there an automatic allocation of DNS and win servers?

1. First, log in to the router settings page to check whether the DHCP server settings are correct.

1 Click Start, click Run;

2. Enter and click OK;

3. Right-click on the local connection and click Properties;

4. Double-click Internet Protocol version 4;

5. In the pop-up dialog box, click Use the following IP address and use the following DNS server address, enter the correct address and click OK.

It is specified that there is another DHCP server in the LAN.

The assigned IP is not an error address and is OK with DHCP.

It's hard to come across this situation, and it's very difficult for DHCP to have the wrong IP address as you said. How can you tell if it's the wrong IP address?

This is the right note for you:

As long as this network cable is plugged in, all PCs in the LAN cannot get DNS, but they can get IP....

This is offline. Should have brought a router. The router may have DHCP configured for which DNS is not configured

The above can be explained:

But you can get the IP, manually configure the DNS to open the web page, and unplug the network cable to work normally.

Because you can't get up by plugging this cable into the computer network card, and you can't get up when you change the crossover cable.

Generally, it is caused by the incorrect rate and duplex settings of the network card, explanation: plugging in the switch can work. Explain that the line has its own rate and duplex.

If you plug in this network cable, you can open the web page by manually configuring the DNS, but the speed is very stuck, and sometimes you can open the connection, sometimes you can't open the connection, which is more suitable for the above explanation.

In fact, there may be worms or LAN viruses on PCs under this line, and there may be loopback phenomena.

Generally, it can be viewed by using a packet capture tool

The simplest thing is to pull it out, wait for which department to declare, know which department the line is going to, and then check the line.

Configure the router WAN port to the WAN port and DHCP with DNS.

Isn't it possible to manually configure an IP address? DHCP is messing up or you can bind a Mac to your office computer

Problem description: My unit has 25 computers, one HP server (Windows 2003 server, DHCP assigned IP), the server network card is called to sell 1 to telecom, and the network card is 2 to the switch. The IP address of NIC 2 is reserved in the server DHCP, the IP assigned by the other clients is, and the gateway is. If you install a domain controller on the server, you must install DNS, how is the DNS on the server configured?

How do I configure DNS in a client's network connection, is it set to auto-fetch, is it set to telco's DNS, or is it set to a gateway server? Hope to give a little more detail! Thank you.

Analysis: 1To install DNS, the IP of your network card 2 must be a fixed IP, that is to say, you can't use DHCP to keep the automatic allocation, you must fill it in by hand (, and then have the DNS of your network card 2 to fill in the telecom or yourself (, you can also fill in the first DNS is and change the telecom (specifically according to the telecom to your DNS to determine the IP, spare DNS fill in your own IP (; NIC 2 cannot be filled in with the gateway.

2. After the DNS installation is completed, you can install the domain, and you can configure DHCP after the domain is installed.

3. The DNS of the client can be automatically configured with DHCP, the configuration of "first" DNS is, the standby DNS is the IP of the telecom, and the gateway is configured as.

4. Common**qq***

First, check whether your wireless network card has manually set the parameters, whether the DNS is automatically obtained, or whether the settings are accurate.
