But it doesn't show as occurring in the localsessionmanager log. Please.does anybody have any clue about this?Ĭould you post the whole error from the event log that references this error 40? According to this page, event 40 is a licensing issue. Or maybe I've stumbled upon a secret code list known only to key individuals at Microsoft, the CIA, and the NSA. My guess is that I'm missing something that's right under my nose. I also have not found a single reference to Event ID 40 in this specific log. But I have searched just about everywhere I could think of and I haven't found any reference to these codes. 5 and 11 are pretty rare.ĭoes anybody know what these reason codes mean? I assume that interpreting this code would give me some insight into the problem(s) we need to correct. 12 shows up a significant number of times. The text is something like ' Session 8 has been disconnected, reason code #.' I see four reason codes: 0, 5, 11, and 12. In the Microsoft-Windows-TerminalServices-LocalSessionManager/Operational event log, there are a lot of instances of Event ID 40. Of course, we have a huge number of variables and we're trying to track down each possibility. We have a Server 2012 R2 terminal server farm and we're experiencing random disconnections.
