![LSASS.Exe 在 SBS2003 上的 CPU 使用率为 100%](https://linux22.com/image/611021/LSASS.Exe%20%E5%9C%A8%20SBS2003%20%E4%B8%8A%E7%9A%84%20CPU%20%E4%BD%BF%E7%94%A8%E7%8E%87%E4%B8%BA%20100%25.png)
LSASS.exe 在我的 SBS2003 DC 上占用了 100% 的 CPU 使用率。
我怎么也想不出是什么原因造成的。我检查了事件日志,发现了一些问题。我看不出其中有什么相关之处。除了 ActiveSync 错误(很久以前开始的,在出现此问题之前)之外,没有其他问题会定期记录。

这是此域中唯一的服务器。我假设问题出在这台机器上,因此我一直在关注本文的第 2 部分;
我尝试了几个我见过的选项。我在 HKLM\System\CurrentControlSet\Control\LSA 中的通知包中有一个条目“RASSFM KDCSVC WDIGEST scecli dsrestor”。我读到这里的标准条目不包括 dsrestor 条目,但我犹豫着说这是问题所在(我今晚有停机时间来测试删除它 + 重新启动)。
有人知道我可以尝试什么吗?
谢谢!-Ewan

好的,我找到了问题。我真傻 - 我没有注意到有重复的 LSASS.exe。原来这是恶意软件挖掘比特币,因此 CPU 使用率很高。
