Recently, like some of you, I've been going through the process of upgrading/migrating my services from Server 2008 to Server 2012-->2016. I also recently upgraded our ESX host to version 6.0, and will upgrade again to 6.5 (the newest version my server is compatible with) in the coming weeks when I can schedule a maintenance period.
Some of my VMs have now been going offline intermittently. I have to disable and reenable the NIC on the VM to bring it back online. I've been checking through windows logs but cannot find much. I've heard recommendations to upgrade VMware tools, which I've done for these servers.
What can I do to trouble shoot this?
Are there logs on the host that will give me data on this?
Thank you all.
