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.
