Hello,
I manage an IT park with about a hundred workstations, and following an update of our servers, I need to assign a new DHCP server that does not have the same IP as the old one, which will change the IP configuration of the workstations.
The problem is that the workstations have 30-day leases and links to network printers that are on DHCP reservations. We are integrating a new VLAN for our printers, so the workstations will not be able to communicate with the printers with their old configuration. Is there a command to force a new ARP request on the workstations globally rather than having to do it one by one?
I hope I have explained my issue correctly.
Thank you in advance :)

Hi,
ARP is not DHCP ...
now, proxy ARP does exist and it's somewhat for that, but it does require some coding.
For the DHCP server, you just need to remove the old one, but it's true that a 30-day lease doesn't help.
But just asking the users to restart their machines should be enough.
Often, it can't hurt and anyway, they should be doing it tomorrow morning, logically.
