Error: You do not have access to this dhcp server

I setup a new windows 2003 R2 DC server. Old one was Windows 2000 SP4.
I moved the old dhcp server from windows 2000 to windows 2003, following

Now, when starting the DHCP server service with administrator credentials. I get a Access denied when viewing the server in dhcp manager. I get it on both old and new server.

I have tried uninstalling both DHCP servers, both it still gives me the error on my new server.

I don't know which thing fixed it.
I read somewhere that I should put the server itself in the DHCPAdmin group.
I also completely uninstalled all traces of DHCP. I rebooted the server, and when i came up again, I used the "add server role" wizard to install DHCP. I dont know if this circumvented the error because it ask you to configure DHCP settings before it starts the service itself.

And by the way, I have deleted HKLM\software\microsoft\dhcp server on both machines.
Deleted C.\windows\system32\dhcp on both machines also.
I am guessing its hiding in ad
Have you authorised the DHCP Server in AD?

Select Start, Programs, Administrative Tools, DHCP.

In the console, right-click DHCP and select Manage Authorize Servers.

Click Authorize in the Manage Authorized Servers window.

Enter the name or IP address of the DHCP server to be authorized, and click OK.

Do you get the error after you've installed the DHCP Service on the new Server and before you've tried importing the old database?
mathiesen-dataAuthor Commented:
I don't know, because I do this often, so I didn't even check the old one to see.
I just used the commands to move it.
I would think I could start the "DHCP SERVER" service with localsystem, but it gives me an error 1079 when trying:

Could not start the DHCP Server service on Local Computer.

Error 1079: The account specified for this service is different from the account specified for other services running in the same process.
You need an account in the local admins group to be able to start the Service and if I remember correctly an ENTERPRISE Admin to load up the database.

I'd try getting the service started without the imported database first, just to confirm that you can and then try and import the old database.

If you make enterrpise admins a member of the local admins group on the Server and use an Enterprise admin account you should have no problems.

It already is.
At this point I just want to configure a whole new DHCP server.
Forget about the old ones, and just get it up and running. However, I cant! :(
I keeps giving me access denied as per screenshot, even if I delete the mentioned registry keys, and delte the dhcp folder after uninstalling dhcp.
