the hostname for each DHCP-enabled device matches the DNS entry for
the assigned IP address. This verification process automatically occurs
when you either run the utility or click
Refresh

DHCP server, or if you cannot contact the network administrator
to change the DNS entry.

option if you cannot use the hostname assigned by the DHCP
server. Contact your network administrator to obtain a valid IP
address, subnet, and gateway. This option disables DHCP on the
device.
•

Use this option to change the
hostname to a name other than either the configured hostname or
the name assigned by the DHCP server. Contact your network
administrator to obtain a valid name.

Keep the existing hostname

the previously assigned hostname. If you select this option,
contact your network administrator to change the DNS entry.
