ntds.dit ntds.dit是主要的AD数据库,存放在C:\Windows\NTDS\NTDS.dit,包括有关域用户,组和组成员身份的信息.它还包括域中所有用户的密码哈希值.为了进一步保护密码哈希值,使用存储在SYSTEM注册表配置单元中的密钥对这些哈希值进行加密 获取方式分为两种: 1.在线获取 2.离线获取 注意: 在域环境中,建议不要直接在线获取hash,特别是域环境比较大的时候,在线获取hash等待时候较长,工具占用资源太多,容易造成域控服务器崩溃. 在线获取 适用于域用户较少的

1.前言 本文的上篇<IM消息送达保证机制实现(一):保证在线实时消息的可靠投递>中,我们讨论了在线实时消息的投递可以通过应用层的确认.发送方的超时重传.接收方的去重等手段来保证业务层面消息的不丢不重. 但实时在线投递针对的是消息收发双方都在线的情况(如当发送方用户A发送消息给接收方用户B时,用户B是在线的),那如果消息的接收方用户B不在线,系统是如何保证消息的可达性的呢?这就是本文要讨论的问题.(本文同步发布于:http://www.52im.net/thread-594-1-1.html)

题意: 统计一段区间内不同数字之和.如1 1 2 3 1 统计2---5即1+2+3. SOL: 很少打过离线的题目...这种可离线可在线的题不管怎么样一般都是强行在线... 考虑这题,此前做过一个类似的题----POJ的染色,那个题目因为颜色不多,可以用二进制记录状态水过.而这个题目刚开始没有什么想法...更别说带更改的题目了(不过貌似树套树还挺好写的...). 网上的题解都模模糊糊...看了将询问排序就有点醍醐灌顶. 没有修改的这样的询问有什么特点与优势呢? 前面的数对后面没有影响-----
