Windows Event Logs and Domains
Windows writes down what happens; learn to read the logon events defenders check every day, and what a domain is.
By the end of this lesson you can explain what the Windows event log is, read a successful logon (event 4624) and a failed logon (event 4625), spot the "many failures then a success" pattern, and explain what a domain, a domain controller and Active Directory are. There is no lab in this lesson: the commands are shown with the exact results they printed on a Windows Server lab machine, so you can read along and answer the questions.
