In a large-scale LAN, network management generally uses DHCP servers to uniformly allocate TCP/IP configuration information to clients. However, the sky is unpredictable. Human misoperations or other factors may cause configuration errors or loss of the DHCP server. What should I do?
Manual recovery is very troublesome and requires a lot of work. At the same tim
First, configure DHCP options
DHCP can allocate many optional parameters in addition to the IP address and subnet mask that can be assigned to clients automatically. , these parameters are DHCP options. Here are a few common:
003: Router: IP address of the default gateway for the IP subnet where the DHCP client resid
The school room is a Windows NT network, configured separately as a subnet, connected through the hub with the upper level switch, and then through the router to achieve access to the Internet.
The server is used as a DHCP server, responsible for assigning IP addresses, and also as a file server backup room of various
DHCP introduction:
The original name of DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) is a LAN network protocol that uses UDP protocol for two purposes: an IP address is automatically assigned to an internal network or network service provider. The IP address is described in RFC 2131 as a central management method for all computers. DHC

I found out how to migrate the print server simultaneously during AD migration. Here, I will continue to talk about migrating server issues in a new ad environment. Recently, one of the migration projects that I've done requires migrating the DHCP server from the original domain to the newly created domain (obviously b
From: The configuration and application of the DHCP server under RedHatEnterpriseLinux6.3 has set up a DHCP service on the newly installed RedHatEnterpriseLinux6.3 Virtual Machine. After the configuration file is complete, the dhcpd service cannot be started. I found the problem only today when I checked the detailed information of the
DHCP services can be configured on many platforms. So here we will mainly explain how to use option 43 on the Linux DHCP server to implement the H3C AP to automatically contact the AC for registration. The original DHCP Server was deployed on the switch, but the
We all know that DHCP can manage a large number of IP addresses and is an essential part of networking. As an administrator, we should better understand this knowledge. Next, we will explain how to configure the windows DHCP server.
Each DHCP server must have at least one ad
Configuring a DHCP server with RedHat9.0 is actually very easy !! But you need to pay attention to some issues: 1. The dhcp Service cannot use cross-network segments only over the Intranet, but not over the Internet. 2. If a virtual machine is used for simulation, you need to disable the virtual dhcp3, and do not allow two dh
Experimental background:
In the enterprise network environment in the absence of DHCP server configuration, often encountered such a situation, users do not know how to configure IP address; IP addresses often conflict; an administrator can frequently make an error in a single configuration of an IP address; customers of laptops often move from one subnet to another. There is a need to manually replace the

First, Concept chapter
In the introduction of troubleshooting DHCP before the first to clarify a few conceptual things, only theoretical enrichment, in order to better understand the following troubleshooting ideas.
First: What data can the DHCP service provide? The DHCP service is not omnipotent, he can only provide network-level-related parameters, such as IP
First, understand the DHCPThe DHCP service provides a mechanism for dynamically specifying IP addresses and configuration parameters. There are both dynamic and static methods.Second, RPM installationIt's very simple because it's with samba.First find the main program and several sub-programs RPM installation package. It should all be in the server package of media DVD. Locate the file location with find an
