Windows Authenticated Scans (logs and results)

Hi All,
we’re doing an authenticated scan on Windows hosts with GVM (version 20.08.1). The GVM was built from source (below you can find the details).

We have performed, on the same Windows hosts, an unauthenticated scan.
The results we obtained are very strange: we discovered more vulnerabilities on the hosts using an unauthenticated scan than the one with authentication. How this is possible?

Also, we were unable to find any log about the successfull or unsucsessfull auth of the user (we are talking about the user we used to perform the authenticated scans) in the GVM logs. Where we can find this infos? In which log file?

Thanks a lot
