Error with adprep /domainprep /gpprep for 2008 R2

Question

While prepping our 2003 forest for 2008 R2, I am getting an error running 'adprep32 /domainprep /gpprep' in one of my child domains.  The forestprep ran fine and domainprep ran fine on all of the other (8) domains -- it's just this one that is giving
me fits.
The error is the apparently common "Adprep was unable to complete because the call back function failed."  The key lines from the log files appear to be:
[2010/06/11:11:15:53.088]
Adprep was about to call the following LDAP API. ldap_search_s(). The base entry to start the search is cn=a3dac986-80e7-4e59-a059-54cb1ab43cb9,cn=Operations,cn=DomainUpdates,cn=System,DC=sa,DC=convergys,DC=com.

Error message: (null)
I have checked all of the known causes of this problem (http://technet.microsoft.com/en-us/library/dd464018(WS.10).aspx) and verified that none of these are the
cause.
When I look at one of the other child domains where this ran, both of those regkeys exist. Based upon the whenChanged and whenCreated attributes, cn=a3dac986-80e7-4e59-a059-54cb1ab43cb9 appers to be a product of this schema change, but cn=446f24ea-cfd5-4c52-8346-96e170bcb912
has a whenCreated date of 12/11/2003 and a whenChanged date of 12/29/2005, which makes me wonder if this key is maybe the product of an earlier schema update that perhaps failed in this domain?
This is driving me nuts. Can someone help?  If not, I'm going to have to open a Premier incident and I'd really like to avoid that.
Thanks.

Hi,
FYI.
On July 1st we will be making Windows Server 2008 R2 General forum read only. After receiving a lot of feedback from the community, it was decided that this forum
is a duplication and therefore redundant of the
General Forum. So, until July 1st, we will start asking customers to redirect their questions to the
General Forum. On June 11th, CSS engineers will move any new threads to the
General Forum.
Please post a reply to
the announcement thread
if you have any feedback on this decision or the process. You can also email
[email protected]
