Hi all,
I have a client getting the following Event ID 529 in the Security Event
log.
Reason: Unknown user name or bad password
User Name: asdasd
Domain:
Logon Type: 3
Logon Process: Advapi
Authentication Package: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0
Workstation Name: <servername>
Caller User Name: <servername>$
Caller Domain: <domainname>
Caller Logon ID: (0x0,0x3E7)
Caller Process ID: 808
Transited Services: -
Source Network Address: -
Source Port: -
This error is happing once every few seconds. I believe they have someone
trying to hack in. I need to know how to tell if it's coming from inside or
outside and how I can help minimize the risk. The username changes to all
manner of combinations. I definitely looks like a hack attempt. We are using
a strong password on the server and I believe we have all non-essential
ports closed.
All help is appreciated,
Lesa
