Search: Find all users who logged into a specific computer.
The primary logons to a computer are logged as:
- Successful Logon (ID: 528)
- Service Ticket Request (ID: 673)
On top of Successful Logons (ID: 528), logons to remote machines might be logged as a Service Ticket Request (ID: 673). Service Ticket Requests are more accurate when using Log Fidelity's solution because domain controllers log multiple identical Service Ticket Requests during the entire session when the user is logged on, but Log Fidelity's solution filters out all the multiple Service Ticket Requests and only logs one Service Ticket Request when the logon actually happens. The only difference between Successful Logons and Service Ticket Requests is that the IP logged by a Successful Logon 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 Service Ticket Request is always the IP Address of the computer being logged onto.
PREREQUISITES
The name (aka sAMAccountName) of the computer.
ESTIMATED QUERY TIME
< 1 second.
METHOD 1 (Quick Search)
1. Enter in the computer name in
the Quick Search field and click Go.
2. (If needed) Turn off "Activity logs BY object" and "Activity logs TO
object"
3. (If needed) Turn on Smart Filter and disable any events that contain
information that does not contain logs you are not looking for.
Note: A Service Ticket Request is also logged when the user authenticates via Kerberos (for example Outlook uses Kerberos to authenticate to a Microsoft Exchange Server.) In this scenario, you can use the Smart Filter to filter out Kerberos authentications that are not logons.
METHOD 2 (Advanced Search)
1. Enter the computer name in
the Target Name field.
2. Select Logon Events only.
4. Select "Success" in the Type field.
4. Click Submit.
LIKELY SCENARIOS IT APPLIES TO
- You want to know who has been logging in to make changes to the computer.
- You want the usage information on a computer.
- The computer was used in a security incident and you want to find out who was logged on during that time.
FINE TUNE YOUR SEARCH
If you know the time scope, domain of the computer, or want to restrict your searches to users in a specific domain you can fine tune your search.
