I created a basic DHCP setup through iManager, as we only have one subnet 190.168.0.0/24 and one dhcp server by
1) creating a DHCP server
2) created a subnet
3) created address range.

When I load dhcpsrvr.nlm I get the error

Server-5.70-63: DHCP Error : DHCP UDP server port (67) registration failed.

Any ideas.

Chris.
