Hi Tore
Did you find a solution to this? We're seeing it in our estate. Approximately 15% of VMs end up with no networking and removed VMware Tools after auto-upgrade that occurs at the same time as a Microsoft Update operation. We've only seen this with VMware Tools 11.2 and later.
We think it's related to the dependency on newer Visual C++ runtimes which would get installed by the VMware Tools installer. These need a reboot, after which VMware Tools is upgrade, expect sometimes Tools is removed, but not reinstalled.
As yet, we've not found a common cause, so we're thinking some sort of race condition, but I can't reproduce the problem on demand. We had a case open with GSS, but they basically said 'upgrade tools manually', which I disagree with as we've always auto-upgraded VMware Tools (for years) without issue.
Thanks
Mike
