This event is generated when a logon request fails. It is generated on the computer where access was attempted.
The Subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe.
The Logon Type field indicates the kind of logon that was requested. The most common types are 2 (interactive) and 3 (network).
The Process Information fields indicate which account and process on the system requested the logon.
The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.
The authentication information fields provide detailed information about this specific logon request.
- Transited services indicate which intermediate services have participated in this logon request.
- Package name indicates which sub-protocol was used among the NTLM protocols.
- Key length indicates the length of the generated session key. This will be 0 if no session key was requested.
我不应该担心这些吗？
我的 SQL Server 也遇到了很多同样的问题，但我刚刚在防火墙中将其关闭以供公众使用。
答案1
您的主机头可能与计算机名称不匹配。这是 Windows 执行环回验证以防止中间人攻击。您可以禁用它（HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\DisableLoopbackCheck）或将主机头添加到注册表：
- 编辑 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0
- 添加一个名为 BackConnectionHostNames 的新多字符串值。
- 修改“数值数据”框中的新 BackConnectionHostNames 键，在单独的行上分别键入 CNAME 或 DNS 别名
- 重启

不，这是 IP 地址为 109.230.245.242 的德国黑客试图通过脚本入侵您的系统！只需屏蔽该 IP 地址即可。他经常在网上活动。
