dcdiag - Starting test: KnowsOfRoleHolders - DsBindWithSpnEx() failed with error 1722

Ran DCDIAG on my domain controller which resides in another site (This is
just an additional domain controller) and I receive the following error on
it.
SRV2 is the Schema Owner and Domain Role Owner. I appreciate any kind of
info and how to fix this replication problems. I did ran a portqry and I had
problems with 3 out of 4 ports not listening. I am not sure whether that
might be the reason, but just a thought. But, I will leave it to the experts
to get back. I have also posted in my previous posting in networking group
about the portquery what I did and the results of it.
