Hey all,
Just recently set up a server 2012 essentials domain for a client. Domain was set up from scratch. Since the set up we've been seeing multiple Event ID 4625 entries in the security logs: An account failed to log on.
Subject: Security ID: SYSTEM Account Name: THISPC$ Account Domain: THISDOMAIN Logon ID: 0x3E7
Logon Type: 3
Account For Which Logon Failed: Security ID: NULL SID Account Name:
Account Domain:
Failure Information: Failure Reason: Unknown user name or bad password. Status: 0xC000006D Sub Status: 0xC0000064
Process Information: Caller Process ID: 0x2c8 Caller Process Name: C:\Windows\System32\lsass.exe
Network Information: Workstation Name: THIS WORKSTATION Source Network Address: - Source Port: -
Detailed Authentication Information: Logon Process: Schannel Authentication Package: Kerberos Transited Services: - Package Name (NTLM only): - Key Length: 0
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.
I've been researching this issue for the past 2 hours, but I'm not having much luck with solutions, or finding the root cause. Exchange is not running on this box. This is only running AD,DNS...
Anyone experience this before? I confirmed there's no malware, I've run nltests on the domain controller which return NO_SUCH_DOMAIN... so I'm not too sure where else to go...
Thanks in advance for the help
