    Okay, to set this question up, I'm using Windows 7 x64 Home. File and Printer sharing is turned off and so is Network Discovery. I'm using Outpost Security Suite Free as my software firewall. Now, when I go to GRC to test my ports, everything is stealthed according to its results. However, when I go to PCFlank, it reports ports 135, 137, 138, 139 as visible.

    It has to be one or the other, it can't be both..so can anyone shed some light on what may be going on and how I can remedy it?

    I've seen different results between those two services as well. Is pcflank scanning the same ip address as shieldsup? Because you're using Outpost, I suspect you're completely stealthed, and pcflank is scanning something else, maybe your router if you're using one or your isp.

    Yeah it shows my "real" IP on both websites. I do run a router, yes, but that would confuse me more. If the router is being scanned, shouldn't it also be stealth or closed on both websites?

    There is a simpler explanation. Pcflank is known to be not very reliable in terms of scanning results. So watch out, it can be simply a pcflank flaw. Try to check with other scanning services....if any around :)

    I tossed out Outpost, so it makes no difference now :D

    If you're using a router, it's not going to make a great deal of difference which software firewall you use, unless your router is full of holes, or you place the PC in the DMZ.

    Images from Windows 7 x64 firewall turned off. No additional security applications installed.

    First image = PC in DMZ
    Second Image = PC not in DMZ
