I'm confused and worried myself here in attempting to perform Exchange Server 2010 SP3 AD schema update.
because previously, when I tried to apply SP3 AD attribute update, it failed as described in this thread
it was due to my DOMAIN\User account was unable to see the default built-in Microsoft Exchange AD security group. I realized that using the DOMAIN\Administrator I can see the default security group.
Now what confuses me is that when running the DS query command to get the current Exchange 2010 SP2 Schema version, it returns 14734 which is saying that the AD schema is already on SP3 ?
Can someone please clarify what is the correct AD Schema version for SP2 ? and what can I do to make sure I can execute setup.com /PrepareAD
command successfully on the Schema Master role ?
