Explanation

When a duplicate IP address exists on the network, ARP (Address Resolution Protocol) conflicts arise because two devices are responding to the same IP. The ipconfig output would show the IP is configured correctly on the new NIC, but ping would fail or behave erratically because another device is already using that address. The OS may also display a 'duplicate IP address detected' warning. The other options (incorrect default gateway, DHCP misconfiguration, incorrect routing table) would typically produce different symptoms such as inability to reach remote networks or failure to obtain an IP lease, not the specific conflict pattern described.
