May want to check for stale or incorrect records in DNS console. Also try
ipconfig /registerdns on the problem DC and on problem member do
ipconfig /flushdns or try to RDP the ip address instead of name. Also might try from PowerShell from source and target.
Test-NetConnection -ComputerName "192.168.49.142" -CommonTCPPort "RDP" -InformationLevel "Detailed"
