I have a  Windows 2003 AD and ADC.Most of the user accounts are  keeps being locked out randomly.
I found con-flicker virus on the network . I believe may be because of this or   any service / application that is trying to automatically authenticate against Active Directory with user accounst.

What will be the best way to find out where the service / application /computer/virus is running that is  trying to authenticate with my account; since its a network with 500 users.

We are using forefront client security as antivirus.

You can start with the steps here  


That will give you a link to the account troubleshooting tools

In this case you have already have the culprit though (Conficker)  When there are random unexplained lockouts in mass it is almost always conficker (at least for the last few years)

Keep doing your best to get rid of that.

And if your goal is to enumerate all the services you have running on all your servers and see where an account might be configured with your account instead.

One way you can accomplish this is via a PowerShell script using the WMI - that startname property tells you what account a service is configured with.

 C:\PS>get-service -name winrm -computername localhost, Server01, Server02  | format-table -property MachineName, Status, Startname, Name, DisplayName -auto

You would probably want to pass the server list as in get-service (gc servers.txt) .........
