NetBIOS Brute Force of Accounts - QID 5005

Qualys flags some of our Windows servers with this vulnerability.  According to the documentation:


QID 5005. NetBIOS Brute Force of Accounts. This QID is returned when brute forcing of a Windows host was successful. See the Result section of the vulnerability for a list of login/password combinations that were successful.



User name:Administrator

Password: (empty)


I don't believe Microsoft allows blank passwords via remote connection. I also tried:  net use \\<ip address>\c$ and various other methods with no luck.

And so my question is how does Qualys exploit this vulnerability on a Windows box and how can I recreate?  Thanks -
