Why do browsers and file explorer use "anonymous" to try to login via FTP. Even with credentials provided?
We have setup a FileZilla Server. Anytime a user tries to login with file explorer, IE, or Chrome, we get "anonymous" login attempts. The log below is just 1 person accessing via IE.
With it doing this, FileZilla anti-hammering kicks in and then increases the delay between logins and folder access.
I understand why it does it, what I cant seem to figure out is how to explain it to a programmer (bossman) that we need to use an FTP client over file explorer, and why IIS did not have issues with this.
