试图追踪 SVCHOST.exe 正在使用的用户帐户

我在我的环境中遇到问题，我的几乎所有 Windows 7 系统（绝大多数基础架构）都试图登录到一个旧的禁用帐户。我知道这是来自以前的系统管理员，他将此帐户用于某些服务，我只是无法弄清楚它的设置位置。

我知道该进程在 SVCHOST.exe 下运行，我有理由确定它是运行以下其他任务的进程。

AeLookpSvc
BITS
Browser
CertPropSvc
IKEEXT
iphlpsvc
LanmanServer
ProfSvc
Schedule
SENS
SessionEnv
ShellHWDetection
Themes
Winmgmt
wuauserv

我认为它可能是旧 WUSS 服务器的残余物，但该服务器已退役并退役，所以我无法查看那里。我不知道 SVCHOST 下的哪个子进程/服务正在尝试这些凭据，sec 日志非常模糊。我已经对受影响机器上的注册表进行了全面搜索，并通过机器上的 rsop 寻找对该帐户的任何引用，但我找不到任何东西。
