I'm getting an Event ID of 529

The USER is listed as NT AUTHORITY/SYSTEM

 

Logon Failure:

Reason: Unknown user name or bad password

User Name: anna

Domain:

Logon Type: 3

Logon Process: Advapi

Authentication Package: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0

Workstation Name: JM-APPSERVER

Caller User Name: JM-APPSERVER$

Caller Domain: JACKSMAGIC

Caller Logon ID: (0x0,0x3E7)

Caller Process ID: 5128

Transited Services: -

Source Network Address: -

Source Port: -

 

I'm trying to see where this logon is coming from. I have nothing on the

firewall logs to indicate a remote access and the building was locked and

alarmed.

 

Any thoughts or suggestions?

It's a failed logon, which is generally less of a concern. Which process

on the server has PID 5128?

I'm certainly _not_ a security expert but your report seems to be missing

some useful information -- such as day and time. Is there a possibility

that cleaners or service personnel would be in the building with physical

access to a computer despite "locked and alarmed"? I know of one case, a

long time ago and on a straight-up UNIX system where a night cleaner

brought her child with her on some nights and... Well, you know how kids are.
