远程得到任意远程NT主机帐号List的源代码

类别:Delphi 点击:0 评论:0 推荐:
由于看到前些日子retina里有个不需要预先知道帐号就可以获取一般任意
目标NT主机帐号的功能。几个月之前,我为了弄清原理,就做了一个工具。
这次整理硬盘,发现了这个小工具,这本身并不算什么,因为ISS scanner等
软件都包含了这类功能。但是我希望大家能够通过这个例子,了解一些NT的
API和安全性知识。

-- 完整的code(use Delphi)和一个编译好的zip文件在
ftp://202.96.215.252/incoming/sea/getuser.zip

这里贴一下程序的主要代码段:
unit Unit1;
{ 这是一个演示如何去获取目标NT计算机上用户列表的程序,
由于Win32 API的限制,此程序只能在NT平台上正确运行。
由于是为了演示原理,所以没有使用多线程,也没有考虑太高
的健壮性,希望诸位海涵。欢迎和我联系
