    Hi all,

    I have a pc running Win 10 Pro (I7 with 32 GB of ram) with Hyper-V installed.  It is running 1 VM with OS Windows 2012 as the guest.  This VM is running the Symantec Endpoint Protection Management Console.  It monitors approx. 90 machine in our small business.  When the host pc was on Win 10 1809, I had zero issues and the system was rock solid.  When I upgraded the host to 1903 many months ago, the host periodically started freezing with a BSOD every few days.  The error is always “Synthetic_Watchdog_Timeout”.   Upon Googling this error, I found many users (running Hyoer-V) who have run into the same situation.  The issue for all started with   the installation of 1903.  I have tried all the suggested solutions people have offered (update bios/drivers, change power plan, etc.).  Basically no one has had any success fixing the issue.

    Some suggested upgrading to 1909.  I did that with no change in the issue.  Some also claimed the issue was fixed with the most recent (Feb) 1909 updates.  Again, people found the problem persisted.      The only real solution appears to be going back to 1809 which is not feasabkel at this point in time.  One person on Microsoft Social Technet commented:

    “Finally heard back from the Hyper-V team.  Looks like a “possible” fix is slated last week of March.  So, guess we’ll see then? 🤷‍♂️

    My confidence is not very high, but my hope is. :p”

    This is a less than definitive answer from Microsoft (as expected).  I am not optimistic, but does anyone have any suggested solutions?

      I’m assuming Symantec have no suggestions?

      cheers, Paul

      Yeah… what he said is what I’d check. When I managed a LAN I used Symantec’s stuff and had very good results with both their software and support.

      Thanks all but the issue is definitely not Symantec.   Many users are experiencing the issue independent of the software installed on the virtual machine.  Everything points to Hyper-V and changes that were made starting with 1903.  Thank you Microsoft.

      Sorry Woody, should have included the link.  When you Google  Synthetic_Watchdog_Timeout + Hyper-V,  several links appear about the issue.  The one I zeroed in on is:

      This particular discussion, at the last post, has the quote I mentioned in my first post above.  Thanks!

        I managed to get a quick mention of this into the Computerworld article due out shortly.

        Let’s see if we can get any illumination…
