Windows 2000 provides a range of TCP/IP troubleshooting tools, which are primarily based on command prompt lines, providing powerful tools for diagnosing network problems.

or an international server (the physical unknown of the network server cannot be determined by the domain name). Based on the routing path, it can be used to determine whether the information is sent from its own system to the network, which IP addresses have been used to send traffic to the other server? This is like when the bus departs from the starting point to the terminal, there will be a lot of street signs in the middle, we know the transmission path of our information to better underst

ipconfig to check TCP/IP configurations
Ipconfig is a command prompt line tool for viewing and managing the client's TCP/IP configuration status. In the command prompt line, Type ipconfig and press enter to obtain the basic TCP/IP configuration attributes of the computer, including the IP address, subnet mask, and default gateway.
In the command prompt line, Typ

DHCP Fault AnalysisIi. Client troubleshooting:
DHCP faults mainly involve two aspects: client problems and server problems. First, we will introduce the troubleshooting methods on the client.
Step 1: Go to Start-> Run-> Enter CMD in the task bar to enter the command line mode.
Step 2: Enter
1. Ping Command
Ping is used to determine whether the local host is connected to another host on the network. According to the default settings, the ping command running on Windows sends four ICMP echo request messages, each containing 32 bytes of data. If the network is connected, we should be able to receive four ICMP echo reply messages. The following describes how to use common parameters:
(1) Ping-T host address: Send the echo request message to the host address consecutively, knowing t
What are the commands that the computer performs to release DNS and update IP?
1, press Win+r to open the operation, input cmd and enter;
2, open the command prompt, enter the command: Ipconfig/flushdns, click to return to the local DNS cache empty;
3, Input command: ipconfig/release, and press ENTER to execute, release the local IP address;
4, Input command:
network cable is not plugged in or plugged in to the effect.
Ii. Retrieve IP address information
When the network is unable to connect, the first time to think of is to view their own IP address information. We can enter ipconfig or (ipconfig/all view details) under command Line (CMD) for viewing.
This is normal if we get the IP address of the normal segment of our company network or the I

Windows 2000 automatically starts the DNS Client Service, which provides the Client name resolution and cache service. Your DNS query results are cached locally. When configuring a DNS server, if you do not have a good grasp of this principle, some incorrect operations will often occur.
You can use the command at the command prompt to clear the information in the DNS client cache. Run the "Ipconfig/flushdns" command on the client. If the drive letter

In the debugging process, I used several network monitoring tools under Windows CE to understand that Windows CE can also use the network monitoring tools we usually use to share them with you.Environment Settings

Step 1: Go to Start-> Run-> Enter CMD in the task bar to enter the command line mode.Step 2: Enter ipconfig in command line mode and press enter to check whether the IP address can be automatically obtained.
TIPS: before performing the first two steps, ensure that the IP Address Allocation Method of the client is set to automatically obtain the IP address.
