      @black3dynamite said in New VM keeps turning off:

      UEFI or BIOS VM?
      If UEFI, is secure boot enabled?

      UEFI, Secure Boot is Disabled

      You may want to go into (on the guest) System Properties -> Advanced Tab -> Startup and Recovery -> Uncheck "Automatically Restart"

      That way if you get BSOD, you can see it on the screen.

      Then look for the memory dump like @EddieJennings stated. Then use program @DustinB3403 mentioned to figure out WTH is going on.

      If you don't know if it is the whole host, whip up a linux machine real quick and let it run. If the Exchange server halts, see if you can still access the linux machine. Just an option.

        You've likely checked for this, but are there events in the Application logs that talk about a bugcheck around the time of the shutdown, or does a C:\Windows\Memory.dmp file exist that was created around that time?

        There were no events about a bugcheck around the time of the shutdown. Something I do find curious though, is the fact there isn't a %SYSTEMROOT%\MEMORY.DMP file at all.

          There usually isn't if verbose logging isn't enabled with these types of crashes.

            Will do, thanks for the tips.

              Ah, well it is now, so time will tell I suppose. Thanks again.

                You usually only see it if there was a bugcheck, blue screen, and then it's not 100% of the time -- at least in my experience. So I was curious if on the off chance there was one that you could investigate.

                  I don't know if it's the whole host, or the Guest itself as I don't notice it until I get calls about Outlook not connecting, but I'm finding no reason or cause.

                  Have you determined if the whole ESXi host is doing down?

                    Okay, so I guess maybe it was one of the guest updates or something that fixed it. It hasn't happened once yet. Solved?

                      It always sucks not knowing root cause, but having it working is better then being broken.

                      You might consider setting up some type of monitoring for it temporarily

                        I've had a similar issue a while ago that was caused by a memory leak in Exchange itself. It kept consuming more and more RAM and at the end of the day crashed the whole VM with a blue screen. It was happening like once a week usually on weekends thus I didn't pay too much attention to the issue since nobody complained. However, it got worth with time so I had to investigate what is actually going on and take measures like adding more ram, defragging the DB and so on.

                        Drop some monitoring agent inside the Exchange VM like Veeam One Monitor to be able to understand what's going on or choose something from the recommended tools here.

                          Is the OS licensed properly? I thought it shuts down if it's not, not sure if that still happens.

                            Yea, it's Activated and all that.
