I’ve seen this happen a few times now, while looking at your Virtual infrastructure, one or more client machines is greyed out and shown as (Orphaned).
Or you can do the following, on a machine by machine basis.
1. Right click the affected VM and select “Remove from Inventory” (nothing gets deleted don’t worry.)
2. Select one of your ESX hosts > Configuration > storage > Right click the storage that holds the virtual machine we are dealing with and select “Browse Datastore” > Locate the machines .vmx file > Right click > Add to inventory > Follow the instructions.
