I am receiving an error when upgrading to SP3. Seems its not able to contact the Schema Master since the Exchange server is on the Child Domain and the Schema Master account is on Root Domain and stating to run setup with the /prepareAD parameter which i have never done.

Here's the error:
Setup needs to contact the Active Directory schema master but this computer is not in the same Active Directory site as the schema master.

Setup needs to contact the Active Directory schema master but this computer is not in the same Active Directory domain as the schema master.

Setup encountered a problem while validating the stat of Active Directory Exchange organization-level objects have not been created, and setup cannot create them because the local computer is not in the same domain and site as the schema master. Run setup with the /prepareAD parameter on a computer in the domain and site, and wait for replication to complete.
