I'd make the corrections, check the event logs and if problems persist put up a new set of files to look at.

I'm not able to connect to BAMTORDC01. I can connect from BAMTORDC01 to other DC from ADUC though. I also tested dcdiag netlogons and BAMTORDC01 failed.
I have uploaded full test result I ran from BAMTORDC01 on the same onedrive link.
Please let me know your thoughts.
Thanks!

- A lot of these possibly because of problematic site to site connectivity.
An LDAP client connection was closed because of an error. 1236 The network connection was aborted by the local system.
- I'd work through this one for the Kerberos errors

Thank you. What's surprising to me is that replication is still working with all these errors which is a good so I can work through fixing issues slowly.
Do you think the LDAP issue is the one causing the RPC error?

It may be related to poor connectivity. Connection being dropped.
