Block access to ports as if they were being blocked from a firewall

I would like to know what the methods are to close some ports manually with windows NT/W2k or to simulate that they are closed from the Net.

simplest way to do this is to use TCP/IP filtering for the network interface.

1. Open the TCP/IP Properties window for the interface. 2. Click Advanced. 3. Select the Options tab. 4. Double-click TCP/IP Filtering. 5. Check the Enable TCP/IP Filtering option. 6. Add and remove ports as you wish.
