RE: Strange open ports on windows machines

[Steve McQuade <steve.mcquade () infoseek com>]

Additionally, I usually disable the windows networking protocols by
unbinding them from the external interface.

Generally, if I don't need a service, I disable it.

                        One word:  Firewall.

                        Block all access to those ports from anything
outside or your site.

                        I think there may also be some filtering code
available, but,
                since I don't use it, I don't know anything about it.

                        BTW...  For those of you playing with Windows 2000,
add port 445
                to the list of things that should be blocked from outside
contact.  You
                can do the same sorts of things with port 445 that you can
with port 135.
