This command-line tool configures Internet Protocol Security (IPSec)
policies in the Directory Service, or in a local or remote registry.
It does everything that the IPSec Microsoft Management Console (MMC)
snap-in does, and is even modeled after the snap-in.

IPSecPol has two mutually exclusive modes: dynamic and static. The
default mode is dynamic.

This tool runs only on Microsoft Windows 2000."
