We recently demoted our old 2008 r2 DC that WHD used for LDAP. After adding in a new 2016 DC, all LDAP connections started failing, as in clients could not log in and no LDAP connection was present in the client info. I changed to a different 2016 DC for LDAP and everything started working normally. I'm trying to figure out what the difference could be between the two 2016 DCs that would cause this. Any ideas?
Thanks
