I am running two virtual machines on ESXi 6. One of them is running Windows Server 2008 R2 which is our domain controller. The second machine is a fresh install of windows server 2012 R2. When i was installing the OS second virtual machine (2012), i lost connectivity to my domain controller. I was not able to remote in, tried to ping and after every three replied there was a request timed out. It even kicked me out of vSphere client. After the installation was completed, things were back to normal. And i had connectivity to both the machines.
This morning, it started happening again, i lost the connectivity to my domain controller for few minutes. I had to shutdown my second virtual machine (2012) to make things run smooth.
I checked the event logs and couldnt find anything there. Please help.
