Audit Failures

Can anyone tell me if they have seen this type of audit and what does it
mean? We just started auditing, but I am not sure what this is telling me.
This case seems very ambiguious. The other day there were the same entries
but they had user accounts that I know are fine. One of the accounts is mine
and two others that access our server via a VPN connection.

Thanks,


Event Type: Failure Audit
Event Source: Security
Event Category: Logon/Logoff
Event ID: 529
Date: 3/27/2005
Time: 9:09:35 PM
User: NT AUTHORITY\SYSTEM
Computer: [SERVER_X]
Description:
Logon Failure:
Reason: Unknown user name or bad password
User Name: Administrator
Domain: [SERVER_X]
Logon Type: 3
Logon Process: NtLmSsp
Authentication Package: NTLM
Workstation Name: [SERVER_X]
 
This event occurs whenever the username & password combination fails.
Generally, you will see these in an organization when someone makes a
mistake typing their password. (though occasionally people misspell their
account). Excessive numbers should be investigated.

Since I don't know the details of your environment, it may be caused by
other events. Logon type 3 is accessed system via network. There are also
several KBs that may apply to your situation.

There are many attempts, even from my account. I think is may have something
to do with our VPN. This is happening with users who are working in
workgroups in a remote office and who are tunneling into my network via a VPN
connection.

Does this spark any ideas?

Thanks,
Erin

Sorry, not really a VPN expert.

However, a couple of questions. You do recognize the Workstation Names
correct? They should be systems on your remote office. So each of these
events should have a valid combination of Username, Workstation Name, and
Domain. It sounds like even though you have several logon failure events,
you do have successful logons as well.

Your VPN server and DCs are current on patches and service packs?

As far as VPN goes, I would try to repost with a new subject asking for
assistance with VPN configuration. That should attract the attention of the
VPN experts. Good luck.

Are any users reporting being unable to access the network from the VPN??
You may also find logon events for remote access users in the system log in
the remote access server. --- Steve
