Excahnge 2013 AD preparation fails, The administrative limit for this request was exceeded.

I'm trying to introduce Exchange 2013 into my existing Exchange 2010 organization. Schema preparation ran fine, but AD Preparation is failing with "The administrative limit for this request was exceeded". I figured out that it is related to "otherWellKnownObjects" attribute under "Services/Microsoft Exchange". Apparently this attribute can hold on 11 records about security groups instead of 17. Looks like it might be related to attribute size.

Is there a way to extend this attribute size?

Thanks.
