why are some connections kerberos and others ntlm?

Hello

That's 'negotiate' request from client. On 'negotiate' request, server first
check if kerberos, most safe, is available. If not, it falls back to NTLM.
Sometimes, for example .Net network credential, you can set the client
request options such as kerberos, NTML, and negotiate. With the first two
request, server doesn't negotiate.
