I am migrating to an sbs 2011 server from a sbs 2003 domain , i am not taking any of the AD settings, however i wanted to make a smooth transition, and thought if i shut down DHCP on the original server I could then add new clients which would join the new domain .
My problems arose when i set up the new scope only to find that the new server DHCP service shutdown with the following message;
"The DHCP service has detected that it is running on a DC and has no
credentials configured for use with Dynamic DNS registrations
initiated by the DHCP service. This is not a recommended security
configuration. Credentials for Dynamic DNS registrations may be
configured using the command line "netsh dhcp server set
dnscredentials" or via the DHCP Administrative tool."
When i saw this i checked the DHCP service and found that it had stopped , I then ran "Fix my network wizard" this reported that there was another device which was acting as a DHCP server. I checked the network and the router DHCP router has been disabled, as i mentioned the original SBS 2003 server DHCP had been disabled. and there are no other devices other than workstations. i thought it might be something to do with IP6 as i only configured the IP4 scope on the new server. I am currently stumped but it might be obvious to someone out there ?
