I have searched a number of my reference books, and the MS website but still I cannot find out how to disable/turn off IP ports on an NT or Win2k Server. Are they all registry hacks? Or is it just a matter of shutting down the services which are keeping the ports open?

Thanks for all your help.

In NT, open the Control Panel->Network->Protocol->TCPIP->Properties, on the IP Address Tab, click Advanced, at the bottom of the tab is enable security. Check it, then click on configure, and you can allow and disallow whatever you want.

In 2k, goto Network Connections and Dialup, right click on the entry you want to apply port filtering on, properties,Click on the advanced button, select option tab, select TCPIP filtering.

Hope this helps.

Thanks, that is exactly what I was looking for. Do you know how to determine why some ports are open, or what services are using them?
