adprep LDAP error 0X20

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
Sorry about my post. Did not read all of your posting :(
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?
