I was trying to remove an old dhcp server from the dhcp authorized list.  The server was turned off and was physically removed from the server room.  I attempted to follow the suggestions listed in the url above.  Using the netsh dhcp delete server command I am getting The specified servers are not present in the directory service.  The server is showing up in the authorized server list.  I also deleted the server from the computer list in active directory, but it still shows up.

Have you looked in ADSIEDIT.msc to see if there are any traces of the server here:
1. Browse to CN=NetServices,CN=Services,CN=Configuration,DC=(your domain),DC=local
2. Are there any dCHPClass objects relating to the server you wish to remove, by IP address or by DNS name?
Did you try removing the server with netsh using FQDN, host name and/or IP address?

On speshalysts replay  the error message - There is no such object on the server.

Connect to
Naming Context  select configuration
Under computer  used the default domain controller
Configuration
CN=Configuration,DC=&
CN=Services
CN=NetServices  hade a reference to the old server, which I deleted. Next I continued on listed below -
CN=DhcpRoot
Right click properties
DhcpServers
Edit
Multi-valued String Editor
Selected the old server
Remove

This process removed the old DHCP server out of the Managed Authorized Servers.

Thanks
