  • Q13
    A workstation has an IP of 169.254.0.1 but has no connection out. What is the issue?
    The computer has started pulling an IP address from a DHCP server, so the disconnection must be somewhere within the network.
    The workstation has pulled a valid IP address from a DHCP server, so the issue is likely with the firewall.
    The workstation is disconnected from the network and is receiving an automatic IP address using the APIPA standard.
    This IP address can only be statically assigned to workstations; DHCP should be enabled on the workstation.
