  • Cannot Detect OS reliably

    I am running a scan nmap -T Aggressive -A -v <target>
    It returns the message OSScan results may be unreliable because we could not find at least 1 open and 1 closed port.
    Is there any remedy for this, or does the target have itself hardened too much to prevent this?
    The Unix & Win32 report very different guesses on the OS.
    Nessus uses a remote HTTP Banner to guess the OS, which comes up with yet another result.
