I am getting about 200k of these an hour:

An account failed to log on.

Subject: Security ID: SYSTEM Account Name: TGSERVER$ Account Domain: WORKGROUP Logon ID: 0x3e7

Logon Type: 4

Account For Which Logon Failed: Security ID: NULL SID Account Name: administrator Account Domain: TGSERVER

Failure Information: Failure Reason: Unknown user name or bad password. Status: 0xc000006d Sub Status: 0xc0000064

Process Information: Caller Process ID: 0x334 Caller Process Name: C:\Windows\System32\svchost.exe

Network Information: Workstation Name: TGSERVER Source Network Address: - Source Port: -

Detailed Authentication Information: Logon Process: Advapi
Authentication Package: Negotiate 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.

On my server... I changed my adminstrative username to something else and since then I've been inidated with these messages.

I found on http://technet.microsoft.com/en-us/library/cc787567(v=WS.10).aspx that the 4 means "Batch logon type is used by batch servers, where processes may be executing on behalf of a user without their direct intervention." which really doesn't shed any light on it for me.

I checked the services and they are all logging in as local system or network service. Nothing for administrator.

Anyone have any idea how I tell where these are coming from? I would assume this is a program that is crapping out...

Thanks in advance!
