## Distro
Windows Server 2019
## GSSAPI Impl
SSPI
## Connection Info:
Connecting to SMB share using the IP address. Uses explicit auth. This still occurred on a domain setup with a domain
account, just used IPs so Kerberos wasn't selected
## Notes
* SMB auth is slightly different, it sends a `NegTokenInit2` structure from the server to client that lists all the mechs it supports
* The `NegTokenInit2` structure is slightly different than `NegTokenInit` as it includes the `negHints` field at the same tag `[3]` as `mechListMIC` in `NegTokenInit`
* The client seems to ignore the first message and just starts a branch new SPNEGO exchange with `NegTokenInit` in it's first reply
* Notable it shows it's still trying to connect with an SPN `cifs/192.168.56.10` as we connected with an IP address.
* Includes the `mechListMIC` even though NTLM was the sole mech that was available in the `mechList`
