My boss has had an informal chat with our Symantec account rep, but I haven't heard of any outcome. I would have liked to go to MP4, but we were already in the process of installing SEP 12.1.6 MP3 on our non-prod so that's what goes on prod. We've now upgraded a number of servers from Symantec. Microsoft asked us to run an automated diagnostic tool on one of the affected servers and came back with 'You could either update Symantec or uninstall and monitor the behaviour'. Is anyone else seeing anything similar? Found a fix? Our non-prod environment has already been moved to SEPM and hasn’t experienced similar issues, so that’s another possible cause. cloud Endpoint Protection Small Business (ugh), which is soon to be replaced with Symantec Endpoint Protection Manager. The affected severs are all also running Symantec. The lack of reproducibility makes it pretty hard to diagnose which, if any, might be contributing to the problem. This all seems to have started occurring after the February 2016 patches were installed. I’ve found a few posts on TechNet of users with similar problems, but so far no answers! We have an open ticket with Microsoft, but as the problem isn’t reproducible or predictable all they’ve been able to do so far is set up some basic Perfmon logging on a handful of servers.

After the server boots back up there will be a gap in the event log between when the problem occurred and when the server was rebooted. So far the only fix we’ve found is to reboot the hardware. Connecting to the server console shows the clock on the login screen hasn’t changed since the “crash” and ctrl+alt+del does nothing. Similar story with a Squid web proxy which kept running for a few hours after the OS seemingly stopped responding. For example we had a database server that would still respond to queries via SQL Management Studio but RDP, psexec, remote Event Viewer, and remote PowerShell all time out. The common symptom seems to be a sudden complete loss of OS response, while any app running in memory will keep going. BIOS is up to date on all the physical servers. Some physical (all Dell but different models… T320, R620, M620) as well as VM (some ESXi 5.1 guests, some ESXi 6). For the past few weeks my colleagues and I have been battling with seemingly random crashes of our Windows 2012 R2 servers.
