PowerChute Network Shutdown version 3.1 and 4.0
vCenter Server 5.x installed on a VM or vCenter Server Appliance 5.x, ESXi 5.x , PowerChute Virtual Appliance or PowerChute installed on vMA.
The user account configured in PowerChute Network Shutdown for vCenter Server does not have permissions to access the ESXi host directly. This can occur if the Active Directory Domain Controller is inaccessible during the shutdown sequence and the Active Directory domain account being used cannot be authenticated.
