    GRC Shields Up Test

    Can someone please tell me if this is good or not?

    Attempting connection to your computer. . .
    Shields UP! is now attempting to contact the Hidden Internet Server within your PC. It is likely that no one has told you that your own personal computer may now be functioning as an Internet Server with neither your knowledge nor your permission. And that it may be serving up all or many of your personal files for reading, writing, modification and even deletion by anyone, anywhere, on the Internet!

    Your Internet port 139 does not appear to exist!
    One or more ports on this system are operating in FULL STEALTH MODE! Standard Internet behavior requires port connection attempts to be answered with a success or refusal response. Therefore, only an attempt to connect to a nonexistent computer results in no response of either kind. But YOUR computer has DELIBERATELY CHOSEN NOT TO RESPOND (that's very cool!) which represents advanced computer and port stealthing capabilities. A machine configured in this fashion is well hardened to Internet NetBIOS attack and intrusion.

    Unable to connect with NetBIOS to your computer.
    All attempts to get any information from your computer have FAILED. (This is very uncommon for a Windows networking-based PC.) Relative to vulnerabilities from Windows networking, this computer appears to be VERY SECURE since it is NOT exposing ANY of its internal NetBIOS networking protocol over the

    I would say very good. You are totally hidden from the rest.

    Just means that your computer is not listening for incoming connections on port 139 (or you have a hardware firewall that isn't listening for such connections). "Stealth Mode" is not a real thing in terms of being a standard name for whatever it is they're talking about. Only the Shields Up site uses it. Everyone else says you're quietly dropping requests. Different people will tell you different things about whether it's better to drop or reject, and I don't really think it matters.

    Doesn't really matter, since the ports are closed reguardless.

    The only difference between reject and drop is that reject sends a response that the port is closed and drop just silently drops the packets.
