105627 2002-12-13 04:27:00 I just did the grc.com port probe and it says that my NetBIOS port is open. It says that it is a major for networked PCs but my PC isn't networked so I would it matter if it is open?? I have tried looking through my firewall settings and I can't find out how to fix it. Could this be some windows program that I have allowed???
I use Tiny Personal Firewall

Can someone please help me before I get worried about it?

Once in there delete anything about Netbios. You don't need it.
That will fix your problem

105629 2002-12-13 07:53:00 what OS? you can disable the netbios port tho i find it makes win98se networking a bit touchy. however if you have a firewall it should be blocked. tiny is a good firewall but not a good one for beginners, as its hard to setup correctly. i would suggest trying zonealarm or outpost. tweak'e (174)
105630 2002-12-14 02:27:00 I use Windows 98 and my firewall was setup by my Dad's friend (my Dad claims he knows more than me). I did ask when he was setting it up ages ago if he had blocked the betbios port and he said yes.
I would prefer to use zonealarm or another firewall but it isn't my computer so I just have to go with what my parents tell me!
I will look under the network settings and delete all of that.

105631 2002-12-14 02:33:00 Since your computer is not networked, you may as well make sure that the "share files and printers" options are unchecked, too. You will need the TCP/IP protocol attached to your internet devive (modem?). Graham L (2)
105632 2002-12-14 02:53:00 If Tiny firewall is anything like Kerio (and believe tweake once said they were similar??) , it's not too hard to add a filter rule to block port 139.
In Kerio its done via Administration-Advanced-Add. A trick is to look at what sort of rules are already set up using the edit button, also the help file, then using these as a guide make up one to block port 139 to incoming UDP/TCP and ICMP packets.

105633 2002-12-14 07:31:00 I quite like Steve Gibsons configuration advice at:
<grc.com
as it disables all the open thinggies before you get to the firewall. With the firewall configured properly on top of that I figure it double protection??
