Server 2012 R2 Failed Login

Occasional Visitor

Hi,

I failed logins on a server. That are local.  Started after a user password change.

 

I do not know what is causing it. I think it is local from Sam6 based on Network info below.

 

I do not think it is a service,  Process or scheduled task of some type? I have checked.

 

Any Idea?

 Any way to simplify search

This event is generated when a logon request fails. It is generated on the computer where access was attempted.

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.

Could be a disconnected session from that user on that machine?

Any update ?
