That was it! Thank you so much! It looks like this problem was two-fold.
1. When I installed the Inventory Service on the vCenter server, the software got installed but the windows service "VMware Inventory Service" was never installed/registered. I had to remove and reinstall the Inventory Service.
2. When I reinstalled the Inventory Service, I followed the steps to reregister the Inventory Service to the SSO but I forgot to register it with the vCenter Server. I followed these steps. These were pulled directly from the VMware KB:
To reregister vCenter Server with the Inventory Service:
- Open a command prompt.
- Change directory to:
C:\Program Files\VMware\Infrastructure\VirtualCenter Server\isregtool
Note: If you installed the vCenter Inventory Service in a location other than the defaultC:\Program Files\
, adjust the path. - Run the
register-is.bat
command to update the stored configuration information of the Inventory Service:register-is.bat vCenter_Server_URL Inventory_Service_URL Lookup_Service_URL
Use this example as a model:
