    ****** Update: This task has been successfully completed.

    On Thursday, September 20, between 10:00 am and 2:00 pm, CUIT will be rolling out essential security features on our network switches serving the following buildings:

    Hartley Hall;

    SIC Residences;

    Hogan Hall;

    McBain Hall;

    These updates require end devices such as servers, workstations, printers, access points; etc., to automatically obtain IP addresses via DHCP. Devices that are configured with static (hard coded) IP addresses must change TCP/IP address settings to DHCP, otherwise the network switch will drop all traffic from these devices. Please identify any end devices that are configured with static IP addresses and make the required change(s) to DHCP. This scheduled maintenance is expected to be completed on-time.

    CUIT apologizes for any inconvenience this may cause, but this action is necessary to ensure a more reliable service.  If clients continue to experience issues after the service-interruption hours, please contact the CUIT Helpdesk at:
