I'm running ESXi 5 with VM web servers (IIS) running in the VMs.
One day, for testing purpose,
a) I select one VM & 'reset' it (I guess this reset is equivalent to
forceful powerdown of a physical server)
b) Then from vCenter, I 'migrate' ( = vMotion?) this VM using
vCenter to another ESXi host (in the same cluster) but this
VM failed to join back the NLB group (refer to attachment 1)
