- On DC03 I'd disable the unused adapter
- On dc02 connection properties has a DNS error 1.12.0.61 should be 10.12.0.61

- you didn't post the problem member so I can't tell what issue there might be there.

- Looks like there may be replication problems so I'd check the event logs on each domain controller and correct the issues found.

(please don't forget to mark helpful replies)

I'd check the DHCP server is handing out other domain controller IP's as alternate DNS to the problem members.

  1) the dc are statically assigned and none of them point to this dc including itself.
  2) check dns server nothing is pointing to this dc

    None of that makes any sense.
    
    Please run;
    
    dcdiag /v /c /d /e /s:%computername% >c:\dcdiag.log
    
    repadmin /showrepl >C:\repl.txt
    
    ipconfig /all > C:\dc1.txt
    
    ipconfig /all > C:\dc2.txt
    
    (etc. as other DC's exist)
    
    ipconfig /all > C:\problemworkstation.txt
    
    then put unzipped text files up on OneDrive and share a link
