<div>Just ran the best practice analyzer on an old Exchange server & ran across the error "Missing FQDN in service principal name". I know that I have to run the setspn.exe -a SMTPSVC/ command, but I am a little confused as to what I actually put in there.</div><div></div><div></div><div>The following table contains possible examples of setspn.exe being misused.

It made use of native Windows software such as setspn.exe and klist.exe, to identify SPNs and request tickets respectively. Additionally Mimikatz was required to carve the tickets from memory before the hash could be cracked. Lastly hash cracking software such as Hashcat and John the Ripper did not yet support this format, meaning cracking was done with a (slow) Python script.
