Hello to All!
We have problem with few of our 2008 R2 VM running on ESXi 6.0 host. vNIC is getting disappears from the virtual machine automatically without any intervention and there is no event indicating the removal of the network card found in vCenter task and event, and in Windows Event-viewer except in the below from vmware.log file.

2017-01-31T16:26:09.189Z| vcpu-0| I120: Hot removal done.
we have fixed this issue on two VM's by referring vmware kb-1012225, but still dont know why this happening.
