Closing the PPTP Port Under Windows 2000?

phnork asks: "I have asked many skilled Win2K users and networking specialists how to close Port 1723 in my Win2K system. I have searched the net unsuccessfully, browsed news groups, asked my ISP techies, and even asked my wife. But, although all agree the port normally used for PPTP (VPN) should not be open, no one has taken the time to document how nor post the solution where it can be found. In fact, I have found that most security issues that abound in the Wide World of Windows occur because those in the know, do not. Not even Microsoft! If they did, the solution would be as easy and straight forward as setting up a printer. Networks and security are still relegated to the nether worlds of the 80s where we used to have problems with every printer installation and computers were hauled to a grinding stop by the inability of the protocol lords to arrive at a consensus. But, maybe now the solution is at hand. Now that I have asked for help maybe someone will come forward with those super words, 'Try this...'." What other hard-to-close ports have you found open in your Win2k install. What did you have to do to close them?

Re:Is this all the info you got?

Isn't there an equivalent to ipfilter in the Windows kernel?

Yes. The Win2k has port filtering but it's disabled in the default install. And it sucks at maintaining UDP state (and is not granular enough for my purposes...)

Try disabling the Network adapter

Go to the device manager, show hidden devices on the view menu if necessary, browse to the network adapters and disable the WAN Miniport (PPTP) and others if you like.
As a side benefit you're machine will use less resources aswell.
