Explanation
The key symptom is that IP connectivity works but hostname resolution does not. DNS (Domain Name System) is responsible for translating hostnames to IP addresses. If the workstation points to the wrong or no DNS server, it cannot resolve names - but IP-based communication still works perfectly, which matches the described behavior. A duplicate IP would cause general connectivity conflicts, wrong VLAN would break IP-level connectivity, and wrong gateway would prevent traffic from leaving the local subnet - none of these would allow successful IP pings while blocking hostname resolution.
