Artifact Interpretation

This artifact can provide the destination IP address (or hostname) of an attempted RDP session. It will also provide the SID of the user who initiated the attempted connection, as well as the ProcessID associated with this activity.

This event is logged regardless of success or failure of the RDP session, and must be cross-referenced with other events such as EventID 4624: An account was successfully logged onon the destination host.

If available, a successful RDP authentication is indicated by the event ID TerminalServices-RDPClient/Operational/1027: Connected to domain. To correlate these two Event IDs, compare their Correlation ActivityID field values.

When the RDP session is ended, either due to a failure to connect, a failure to successfully authenticate, or a manual close of the session, TerminalServices-RDPClient/Operational/1105: The multi-transport connection has been disconnected and TerminalServices-RDPClient/Operational/1026: RDP ClientActiveX has been disconnected should be logged, and is likewise able to be correlated by its Correlation ActivityID field. This allows for determining a time span during which an RDP session was in progress.

Example

In the following example, the user with SID S-1-5-21-3471133136-2963561160-3931775028-1001 attempted to RDP to a system at IP address 192.168.116.74. The connection was not successful, resulting in TerminalServices-RDPClient/Operational/1026: RDP ClientActiveX has been disconnected being logged with the same Correlation ActivityID value of {780cf827-0ed1-4f4b-924c-3b14e7660000}.
