Settings for port maintenance on WinNT 4.0

The answer to the May 6 question regarding how to open and close ports addressed where the settings were for Windows 2000. Can you also cover specifically Window NT 4.0?

Yes, you can manage ports individually from NT or Windows 2000. Here's how:

NT -- Open up the TCP/IP properties of your network adapter and check the "enable security" option. Click the advanced tab and you will have the ability to permit/deny individual TCP/IP/udp ports.

Windows 2000 -- Open up the TCP/IP properties of your network adapter and go to advanced. Next go to the option tab and select "TCP/IP filtering." You will now have the option to enable individual port filtering.
