A Workstation Cannot Leave Its LAN
One workstation can reach its local LAN but cannot reach anything beyond it, while neighboring hosts work normally.
Scénario
A newly issued workstation at Palisade Healthcare can communicate with nearby devices on its local LAN, but it cannot reach the internal application server or the external test network. Other workstations on the same segment are unaffected, and no switch or router outage has been reported. Compare the working and failing hosts, identify what prevents traffic from leaving the LAN, and restore end-to-end access without changing the network's addressing plan.
