KDC
Nmap discovered a KDC service running on the taraget port 88
and 464
The running service is Microsoft Windows Kerberos
While I do not know the naming convention that the target domain uses, I will attempt to enumerate usernames as much as possible by brute-forcing the KDC For efficiency, I will get that running in the background while enumerating other services
