error when I try to run adprep rodcprep

I am  migrating from sbs 2008 to 2008 R2 and i get the following error when I rodcprep command.  my level is already set to 47.


Adprep failed the operation on partition DC=ForestDnsZones,DC=Shamrock,DC=local
 Skipping to next partition.
==============================================================================


Adprep detected the operation on partition DC=Shamrock,DC=local has been perfor
ed. Skipping to next partition.
==============================================================================


Adprep completed with errors. Not all partitions are updated. See the ADPrep.lo
 in the C:\Windows\debug\adprep\logs\20121222005220 directory for more informat
on.

To successfully update all partititions, the current logged on user needs to be
a member of Enterprise Admins group.  If that is not the case, please correct t
e problem, and then restart Adprep.er

I reviewed both of these documents.  I am still getting the error.

I am tempted to proceed.  Both /domainPrep  and /forestprep  ran successfully.  Only rodcPrep is the issue.   What is the arm if I proceed to make the Win 2008 R2 a DC without /rodcPred???

it is requiered only when if you are going to deploy RODC
it's no issue. you can run it later when you  deply a RODC

Just to be clear.  I am doing a migration from SBS2008 to 2008 Ent R2.

One of the steps says to run all the ADprep commands before making the  win2008 R2 server a DC on the SBS2008 network.   thoughts????
