Troubleshoot problems on the DHCP client Article01/15/2025 In this article -->This article discusses how to troubleshoot problems that occur on DHCP clients.Troubleshooting checklistCheck the following devices and settings:Cables are connected and working.MAC filtering is enabled on the switches to which the client is connected.The network adapter is enabled.The correct network adapter driver is installed and updated.The DHCP Client service is started and running. To check this, run the net start command, and look for DHCP Client.There is no firewall blocking ports 67 and 68 UDP on the client computer.Event logsExamine the Microsoft-Windows-DHCP Client Events/Operational and Microsoft-Windows-DHCP Client Events/Admin event logs. All events that are related to the DHCP client service are sent to these event logs.The Microsoft-Windows-DHCP Client Events are located in the Event Viewer under Applications and Services Logs.The Get-NetAdapter -IncludeHidden PowerShell cmdlet provides the necessary information to interpret the events that are listed in the logs. For example, Interface ID, MAC address, and so on.Data collectionWe recommend that you collect data simultaneously on both the DHCP client and server side when the problem occurs. However, depending on the actual problem, you can also start your investigation by using a single data set on either the DHCP client or DHCP server.To collect data from the server and affected client, use Wireshark. Start collecting at the same time on the DHCP client and the

In the area of network analysis and troubleshooting, two prominent tools often come into play: Fiddler and Wireshark. While both serve the purpose of dissecting network traffic, they differ in their approach, features, and use cases. FiddlerFiddler is a web debugging proxy tool primarily designed for inspecting and manipulating HTTP and HTTPS traffic. It acts as an intermediary between the client and server, capturing and displaying network requests and responses in an easily digestible format. Here’s what makes Fiddler stand out:User-Friendly Interface: Fiddler boasts a user-friendly GUI that simplifies the process of capturing and analyzing HTTP traffic. Its intuitive layout and customizable views make it ideal for web developers and testers.HTTP(S) Inspection and Manipulation: Fiddler excels at dissecting HTTP and HTTPS traffic, allowing users to inspect headers, payloads, cookies, and more. It also enables users to manipulate requests and responses on-the-fly, facilitating debugging and testing tasks.Performance Testing and Optimization: Beyond debugging, Fiddler can be used for performance testing and optimization by measuring latency, throughput, and response times. Its built-in statistics and performance profiling tools aid in identifying bottlenecks and optimizing web applications.WiresharkWireshark, on the other hand, is a powerful network protocol analyzer that captures and displays network packets across a wide range of protocols. Unlike Fiddler, which focuses on HTTP traffic, Wireshark provides comprehensive packet-level analysis for all types of network communication. Here’s what sets Wireshark apart:Protocol Agnosticism: Wireshark supports hundreds of protocols, including TCP/IP, UDP, DNS, DHCP, FTP, SSH, and more. This protocol agnosticism makes it suitable for analyzing a diverse range of network traffic, from local networks to the Internet.Deep Packet Inspection: Wireshark provides granular insight into network packets, allowing users to dissect protocols, examine packet headers, payloads, and metadata, and perform sophisticated filtering and search operations.Forensic Analysis and Security Investigations: Wireshark is widely used for forensic analysis and security investigations, enabling users to detect anomalies, identify malicious activity, and analyze network attacks such as DDoS, malware infections, and intrusion attempts.Choosing the Right Tool:Use Fiddler If: You primarily deal with web development, debugging web applications, analyzing HTTP(S) traffic, and need a user-friendly interface with powerful debugging and performance
