A weird one this. We are not able to view Hosts or Clusters in the web client. Perfectly fine in the Windows client. We've increased Java memory for Web Services, Web Client Server and RAM for the vCenter Server VM itself, updated vCenter and our clients, rebooted numerous times and restarted Inventory Service.
We're on vCenter Server 5.5.0 2001466 and the Hosts are on 5.5.0 2143827.
If it was the CIM service I'd have thought that would effect the Windows client as well. Anybody have a similar experience?
