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
error?

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

The index mode changed at 4.8.0, this might be more picky i.e. it wont
allow things that 4.7.x would.

If this was a Samba DC, I would suggest running 'samba-tool
dbcheck' on it, but is there a windows version of this tool ?

If 4.7.7 joins and works successfully, have you considered using this
as the main DC and try joining the 4.8.2 to it ?

Apparently there is

Huh, learn something new every day!! :-)

I am going to give that a try.

That also sounds like a good idea.

Thanks for the help.
