In daily network fault maintenance, the most commonly used equipment is the switch, especially the access layer switch, which serves as a bridge connecting users and switching routing devices. The switch acts as an intermediate, it plays a very important role in troubleshooting network faults. If we have an understanding of its own faults, we may be able to help us quickly and more accurately identify and solve problems, we will share with you the

From: http://www.pcdog.com The cause of an error on the IIS server is complex. Errors such as service startup failure, IIS process interruption, or site failure will be recorded in system logs. No matter what errors occur in IIS, you should use the Event Viewer to view related events recorded in system logs before determining the troubleshooting solution. Some errors are apparently caused by hardware damage to the server, while others are often imperc

Network diagnosis is an important technical task that manages and makes good use of the network to maximize its role. This article briefly describes the hierarchical diagnosis technology, discusses the diagnosis of various router interfaces, and reviews the troubleshooting of the connectivity fault of the interconnected network. Network Fault Diagnosis Overview Network Fault Diagnosis: based on the fault phenomenon, the Network diagnosis tool is used

We all know that each computer needs an address to access the Internet normally. This address is what we often call an IP address. How can we effectively manage these IP addresses as network administrators? You can set the corresponding IP address, subnet mask, gateway address, DNS address, and other network parameters for each computer, but it is very cumbersome and heavy workload, conflicts often occur in practical applications. How can we effectively allocate these network parameters? The DHC

Faults are inevitable during network management and O M. If an administrator attempts to build a zero-fault network, it will be futile. There are too many randomness and contingency factors in network faults, not to mention human factors. Therefore, what administrators need to do is to master the network troubleshooting skills, accumulate experience to cultivate a keen sense of smell, and be able to quickly locate and eliminate faults without detours

It is very useful to know some troubleshooting methods for access networks, and it also gives us more convenience in actual use. So I have studied the specific implementation methods of access network troubleshooting, And I will share with you here, hoping it will be useful to you. As a comprehensive technology, network fault diagnosis involves many aspects of network technology. Before learning the concept

DHCP protocol troubleshooting problem. This time, we mainly aim at the failure of clients to obtain IP addresses through the DHCP server. In this regard, what problems should we pay attention to, as well as its analysis and specific handling steps? Next we will look at it in detail. DHCP protocol troubleshooting ◆ Network Environment As shown in. In this networking environment, you can configure a global ad

1. Serial Port troubleshooting When a connectivity problem occurs in the serial port, in order to eliminate the serial port fault, the show interface serial command is generally used to analyze its screen output report content and locate the problem. The start of the serial port report provides the interface status and line protocol status. Possible Combinations of interfaces and line protocols are as follows: 1) serial port running and line protocol

method in the maintenance of the computer. Replacement refers to using normal switch components to replace faulty parts, so as to find the fault point. It is mainly used for the diagnosis of hardware faults, but it should be noted that the replaced parts must be the same type of switches of the same brand and model. Of course, in order to make the troubleshooting work follow the rules, you can analyze the faults according to the following principles.

Wireless troubleshooting is what we will explain the content of this article. To cut into our theme from four aspects. Includes whether it is a hardware issue, how the access point is connected, whether the device is configured incorrectly, and whether multiple access points are not in the customer list. Wireless troubleshooting One, is a hardware problem When there is a problem with the wireless network,

Faults in network applications are always overwhelming. So this time we will explain the IP protocol troubleshooting: The interface does not borrow the address. Let's look at the network structure. IP protocol troubleshooting: Network Environment During a test, configure the interface to borrow the IP addresses of other interfaces. The networking diagram is as follows. Figure IP address borrow case network

After we set up a small Internet cafe, network maintenance is very important to make it work properly. Due to the complexity of network protocols and network equipment, it is not as easy to solve many faults as solving single-host faults. The identification and elimination of network faults require both long-term knowledge and experience, a series of software and hardware tools, and your wisdom. Therefore, every network administrator should learn more about the latest knowledge.A.

eagle-a bit of experience with troubleshooting troubleshooting has been working in the company, and there are often some new problems, but there are also some difficult problems. Let's talk about your own experience in performing troubleshooting. I hope it will be helpful to you. first, we must have a solid Oracle Foundation and have a deep understanding of so

The general flow of software projects is: design, coding, tuning, on-line. Tuning process often encounter system performance is not enough, but the performance is not good also normal, if you write code performance on the cow X a mess, may also not need so many so-called best prticace experience summed up.Recently saw a book, "DevOps Troubleshooting", the book is very thin, the content may be in other books are explained, but he summed up very well, m

Network troubleshooting: Consider the Server Load balancer System It may be difficult to eliminate network problems. If a Server Load balancer system is added to the network, it will pose another challenge. It may not be easy to identify whether the Server Load balancer system is losing data packets, changing data packets in some way, or adding more latencies. However, you can use some tips to make it easier for you to discover problems. The first ste

Troubleshooting of program timing problems in C Language Abstr:] For software that works collaboratively with multiple modules, the timing of program processing is very important. When the order of message processing is disordered, an exception occurs in the program. This article is based on the author's practical project experience. The timing problems between software modules are analyzed in detail, which provides a deliberate disciplinary test for
