DHCP – The specified servers are already present in the Directory Service

After building a Windows 2016 DHCP server I attempted to authorise the server in AD but kept getting the message “The specified servers are already present in the Directory Service”. I have never had a Windows server with this host name so was a but confused.

The solution was simple enough, I opened sevices.msc and restarted the “DHCP Server” service
