Exchange 2010 and Active Directory

Getting Powershell errors and I notice the following:

I have 2 Domain Controllers and both have Microsoft Exchange Service Account OUs but only one

has Microsoft Exchange System Objects.

Is that correct or are the DCs out of sync and if so how to I sync them.  I have tried thru AD Sites and Service but the Object OU never copies over.

Any assistance is appreciated.

Thanks

Dave
