Check it for what? If I understand correctly the error is saying that the target
object is not there. The problem is I do not understand what the target
object is or how to find it. Assuming that the error is referring to 
Partition[DC=example,DC=com] objects[466/7952] linked_values[72/388]
How do I figure out what the error is referring to?

As I said in a separate message, I can successfully join using 4.7.7.
If this is a problem with the existing MS DC, why does 4.7.7 join without

To be clear I am not doubting your advice and I do appreciate it. I am just
trying to understand.
