The installation seemed to go well but I'm seeing odd messages when I show the replication status on both the Samba server and the Win2k8R2 server.  Is there something I missed in the install?  I followed the instructions outlined at https://wiki.samba.org/index.php/Samba4/HOWTO/Join_a_domain_as_a_DC

No, you shouldn't need to add DNS information manually.  The
samba_dnsupdate script should run once Samba starts and handle all this.

As to why things are failing, and your mention of a schema mismatch, if
the import of the exchange schema has caused problems, this might be an
issue.  Are there any more details in the logs?

You might want to try current master, if you are in an experimental
mood, as we have some DRS improvements, but otherwise I'm sorry I can't
help more.

Sorry,
