Diagnose the 169.254 Address

(OBJ.2.6)

Scenario

A workstation can't reach the shared drive or the internet — nothing off this machine loads, though the mapped local printer still works fine. Open a Command Prompt and run ipconfig to see what the Ethernet adapter is actually configured with. It reads 169.254.18.44 with no default gateway. That's not an address any server handed out — it's the address the adapter gave itself. Unlike the front-desk PC on the printer VLAN, this segment does have a DHCP server reachable, so a fresh request should succeed: release the dead lease with ipconfig /release, then request a fresh one with ipconfig /renew. Verify the new configuration with ipconfig before submitting.

These instructions stay visible beside the interface while you work.
