I was in the process of decommissioning a server that was our DHCP server for our phone system subnet. &nbsp;Well on the new server which has the same name as the previous server along with pointing the devices to the same scope of addresses we are getting an error Bad_Address. &nbsp;How can I fix this? &nbsp;The older server has had the DHCP scope removed from it along with being physically turned off. &nbsp;<br />

I would also like to know how to manually remove old dhcp servers that are no longer in existence.
