黑客入侵解决“计算机管理”中用户列表为空的经历
人气:0
最近XPFOX叫我看看他朋友的服务器,说计算机管理的“本地用户和组”的“用户”没有显示的!
我第一想到的就是有人进了服务器,在他朋友的服务器上创建隐藏的帐号,人为错误导致列表不显示!
以前测试隐藏帐号时也试过这样! 我进了他的服务器,在“本地用户和组”下的“用户”,真的是没有显示! 在 CMD 里 输入 net user 可以显示全部帐户 我再去看看 HKEY_LOCAL_MACHINE\SAM\SAM 里是否有不正常的!
我运行“regedt32”把 HKEY_LOCAL_MACHINE\SAM\SAM
下的权限设置为 Administrator 可以查看和修改! 在HKEY_LOCAL_MACHINE\SAM\SAM\Domains\Account\Users\Names
下,没发现有隐藏的帐号,可能是XPFOX的朋友删除了还是怎样(当然是不是他们删除了也不重要了)! 我看了一下权限没什么问题! 好像是很正常的! 但为什么不显示 汗~~~~ 我在“本地安全策略”里也没发现什么大问题! 只见“安全选项”下的
"帐户:重命名来宾帐户" 的帐户名不是 Guest
"帐户:重命名系统管理员帐户" 也不是administrator 执行 "net user" 后发现没有 administrator 有 guest ,我只觉得有点怪怪的!
怎么 重命名系统管理员帐户" administrator 后,就没有 administrator 而 guest 存在! 没有解决问题,只好到网上搜索看看有没有答案!找了好久,有一份资料和此问题有点相关!
内容如下

删除其中一个用户项 [HKEY_LOCAL_MACHINE\SAM\SAM\Domains\Account\Users\Names\mat01$]@=hex(3fb):
重新启动电脑就OK了。 --------------------------------------------------------------------
我看看服务器上的HKEY_LOCAL_MACHINE\SAM\SAM\Domains\Account\Users\Names\
下是否有相同的Hex值 后来发现,Guest 和 "帐户:重命名来宾帐户"里显示的帐号的 hex 值相同!
现在要删除哪一个试试? 我想到 重命名系统管理员帐户 administrator 后,
就没有 administrator ,应该 "帐户:重命名来宾帐户" 改了 Guest 应该也没有
guest 才对! 我先备份 guest 的注册表信息,之后删除,再点击 计算机管理的“本地用户和组"
下的"用户",帐户终于显示了! 后记!
问题出在于“HKEY_LOCAL_MACHINE\SAM\SAM\”下,思路是对的,但不够细心也会使问题不能解决!
