Hi John,

Is your DHCP config complex? - If you only running DHCP on a single
server for a few subnets I would be tempted to force expiration of the
leases and then authorise the new DHCP server.

The DHCP "Conversation" will prevent any duplicate IP addresses being
assigned to a workstation.

This might not be an option for you if you do have a few thousand pc's
to consider but worth pointing out nonetheles.

What does DHCP have to do with domains? DHCP is an Internet standard.
The only link with AD is that the DHCP server must be authorised before it
will issue addresses. This is a safety device to try to avoid multiple DHCP
servers in a network.
