NETSH DHCP SERVER Access Denied

Windows 2003 R2 SP2 DC1
Windows 2003 R2 SP2 DC2

I had only one DHCP server running on DC1 we had a power outage and DC1 was out for a long time.
DC2 was up and running so I decided to add DHCP server on DC2.
My network is 10.2.8.0/22 so I have plenty of address that the scope will not overlay.
I copied all the reservations from DC1 to the DC2 DHCP setup.

Then I authorized the DHCP server and started the DHCP server

Got this event error

Event Type:      Warning
Event Source:      DhcpServer
Event Category:      None
Event ID:      1056
Date:            3/28/2015
Time:            8:33:25 PM
User:            N/A
Computer:      SERV012
Description:
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.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

Then I tried this
netsh dhcp server set dnscredentials administrator mydomain password
access is denied

then
netsh dhcp server show dnscredentials
access is denied

netsh dhcp server show server
the current server is serv012 .............   this works

when I do the above on DC1 no problem it works

DC2 owns all the AD Roles

Any thoughts?

Thanks
