You can use the NetUserChangePassword function in netapi32.dll.

[DllImport("netapi32.dll", CharSet=CharSet.Unicode,
    CallingConvention=CallingConvention.StdCall,
    SetLastError=true )]
static extern uint NetUserChangePassword (
    [MarshalAs(UnmanagedType.LPWStr)] string domainname,
    [MarshalAs(UnmanagedType.LPWStr)] string username,
    [MarshalAs(UnmanagedType.LPWStr)] string oldpassword,
    [MarshalAs(UnmanagedType.LPWStr)] string newpassword
);
