Schema errors when trying to update for 2003 R2

I'm getting some errors when I run adprep /forestprep from CD 2 of 2003
R2.

At the moment we have 5 domain controllers, four are running Windows
2000 and one is running Windows 2003. I upgraded our schema last year
so that we could add a 2003 domain controller and everying went fine
(alghough I did have to run a hotfix from MS because we previously had
Services for Unix installed - I think that's our problem!).

I setup a VMWARE machine with 2003 server SP1 installed and added it to
our domain. I then installed AD on it and transferred the Schema Master
role to it. I then stopped outbound replication, took a snapshot (just
in case) and tried to run adprep /forestprep, but I get the following
errors:

I've checked the parameters on the Microsoft website at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/adschema/adschema/active_directory_schema.asp
and they are not correct. However, I can't modify the entries using
ADSIEDIT as I get an error message about the 'attribute being owned by
the system'.

Can anybody offer any advice on the best way forward? Thanks for taking
the time to read this post.

Jim
