Re: [PEN-TEST] Closing Port 139

Another question on this subject, is the NT TCP/IP filtering stateful or
does it just filter all packets on a port? (I am talking about the OS
filtering, not the proxy server feature)?

     How well does this work on just NT?  I have been told that the NT
packet filtering does not work consistantly with all ports.   I have wanted
to test it but there is just not enought time in the day.

        Both Microsoft Windows NT and Proxy Server provide packet filtering
at the
NIC level.

        It can be accessed from the Security Tab of the Proxy Server
properties and
the network applet of control panel.
