Search: Find the events when a specific user has logged onto a specific computer.
The primary logon failures to a computer are logged as:
- Logon Failure (ID: 529)
- Pre-authentication Failed (ID: 675)
On top of Logon Failures (ID: 529), failed logons to remote machines might be logged as a Pre-authentication Failed (ID: 675). The difference between Logon Failures and Pre-authentication Failures is that the IP logged by a Logon Failures sometimes contains the IP address of the remote computer if the user is logging in remotely via Terminal Service (aka Remote Desktop) whereas the IP logged in the Pre-authentication Failures is always the IP Address of the computer being logged onto. The name of the computer being logged onto isn't logged, but should be easily attainable with the IP Address in the log.
