I'm having an issue in my environment where nearly all of my windows 7 systems (vast majority of the infrastructure) are attempting to log in to an old disabled account. I know this is from a previous sysadmin that used this account for some service I just cant figure out where It's being set.
I know that the process is running under SVCHOST.exe, I'm reasonably certain that it's the process that is running the following other tasks.
AeLookpSvc
BITS
Browser
CertPropSvc
IKEEXT
iphlpsvc
LanmanServer
ProfSvc
Schedule
SENS
SessionEnv
ShellHWDetection
Themes
Winmgmt
wuauserv
I think it may be remnants of the old WUSS server but that server was retired and decommissioned so I can't look there. I don't know what sub-process/service under SVCHOST is attempting those credentials, the sec log is very vague. I've done a full search of the registry on affected machines as well as going through an rsop on the machine looking for any reference to that account but I can't find anything.
An account failed to log on.

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.

None of those services would need to use explicit credentials. The "Schedule" service is the Task Scheduler. You can use the following command to check the scheduled tasks.
Then search File.txt for the account/principal.
