Network IP Changed From Top-Down

    Question

  • Hi,

    Our network admin changed the whole IP range from 192.168.1.X to 172.12.155.X because he needs to install firewall (hardware) on a compromised IP.

    As an AD admin, i have no problem with installing Firewall, however, I have 200+ PCs/VMs in my domain (and could be more in few months).

    Though all of the 200+ have DHCP IP, their DNS was configured to the old Doamin IP.

    The question is, is there a script to change the whole DNS address of all 200+ machines?
