Use a router. I use an old headless P166 PC with smoothwall on it, but any
hardware router/firewall is a good idea IMO.

Use a Cable/DSL Router such as the Linksys BEFSR41 and specifically block TCP and UDP ports
135 ~ 139 and 445 and you won't have to muck with the computer's OS.

I take it TCP/UDP port 305 is a typo as there is nothing from Microsoft or other vendors at
that port loading a Service.

So how do you know the port is "open"?

Yeah. Most of the online scanners are flakey. You go to a couple of
different ones and they are likely to give different results...

i usually use grc's sheilds up as a qick test
and it reported 135 as being open all other ports were cloaked
i disabled dcom and found a few other services i should disable such
as the rpc and remote access services.....
i also set rules to disable access to these ports 135,136. 137.138,139
for udp + tcp in kerio firewall.....port 135 obviously this didnt do
it...still responding to pings from grc
wonder if disabling echo request would do the trick??
i cant test it here as we have a hardware firewall i cant play with

Do you think you just answered your question in your reply ?

As I suggested, use a Cable/DSL Router and specifically block 135 ~139 and 445 on the
Router. You can even get a Router model with a full FireWall implementation.

I have a Linksys BEFSR81and block all WAN requests and those ports and all ports scans from
all sites indicate all ports are stealthed. I have the RPC, NetBIOS and SMB ports open on
all my PCs because I have a SOHO LAN behind that Router. No mucking with the OS needed.

Now it's port 135 (instead of 305)? Did you read the comments on GRC's web
page regarding port 135?

See https://www.grc.com/port_113.htm. It is about a different port but
gives clues as to how you close that port. Basically, define a rule that
kills the port. If you have a NAT router, disable it there. If all you
have is a software firewall in a host connected directly to the Internet
then define a rule to block it there.

the machine in question is offsite. i am going back next week to
attempt to secure it properly.....my friend has no money for a router
so we need to do the job with a software firewall ....as i said we are
well protected here with hardware firewall so i cant do much to test
this .....ip address of his computer is fixed and a previous virus
infection has allowed access to a server that is still attemting to
download virus.....
the only visible port is 135 and that is open....obviously my
knowledge here is deficient as i closed the port to tcp + udp which
did nothing...... my simple question is if i kill the port for icmp
will that cloak it.....i am using kerio pf
thanks again
