NT DHCP

When changing DHCP options we have noticed that the client’s settings will override the DHCP configuration.

EX: NT workstation has DNS server setting of 10.10.10.1. We modify the DHCP server to hand out 10.10.10.2. When the client workstation reboots, etc. it retains its old setting of 10.10.10.1. If the workstation doesn’t have DNS settings, then it will use the new setting received from DHCP.

Is their a way to override possible client settings when using DHCP?
