I'm using dcpromo in a new Windows 2003 server to install the system as a domain controller in an existing Win2K domain.
I get an error saying that the AD version running in the forest doesn't match with the AD version runing in the machine.
(sorry for the translation I'm from Madrid)

So I go to the master an execute adprep /forestprep using the Win2k3 CD. And I get error 0X20 (the entry ot attibute requested does not exist on the directory server) This is the last part of adprep.log :

Adprep ha generado un error LDAP. Codigo de error: 0x20. Codigo de error extendido del servidor: 0x208d, Mensaje de error del servidor: 0000208D: NameErr: DSID-031001BD, problem 2001 (NO_OBJECT), data 0, best match of:
      'CN=Servers,CN=root,CN=Sites,CN=Configuration,DC=rentokil,DC=es'


Do you know what's the problem?

Thank you for your time.

You can not add a Win2003 DC to a Win2000 domain without preparing the forest and domain first to Win2003 level.
Basically you run two preparation commands: 'adprep /forestprep' and 'adprep /domainprep' to modify your active directory.
Detailed instructions here:

hope this helps

Please follow instructions in the following document to verify that your forest is ready for 2003. Mainly focus on 'Domain and forest inventory', section 2:

All the Win2K are SP4, but it's showing LISA-SEV and LISA-VAL that are NT4.0 machines that have been disconected 4 months ago. PROLIANTO is the only NT 4.0 that it's alive (it's our Exchange 5.5 Server) Is the problem these old NTs?

You should remove the two disconnected NT BDC accounts from domain in Server Manager, so that they are no longer seen as DCs.
