A user recently reported intermittent network access issues. While troubleshooting, a notification appears stating that Windows has identified an IP address conflict. There is a DHCP server on your network. When you open the user's TCP/IP properties, it is configured as in this picture. What steps must you take to fix the problem?

The most typical reason of an IP address conflict is when a computer is configured with a static IP address that is in the DHCP server's range. The DHCP server, uninformed that the address has been statically assigned somewhere, distributes the address, resulting in a conflict. Rebooting the device will not assist, nor will releasing the address and requesting a new lease from the DHCP server - it will simply hand out the same address again because it is unaware of the situation. As the administrator, you must monitor the offending user. A packet sniffer is commonly used to examine network traffic and determine the computer name or MAC address related with the IP address in issue.
