Hi,
I just run into the same issue.
It seems that win2008 cannot be added to view as an UNMANAGED machine. I spent half of my day trying to come up with different scenarios and the ONLY way how I could add the win2008 vms to view was when I set the pool as a vcenter based manual or auto pool.
If I selected Other Sources for my manual pool the win2008 vms would not show up.
I found another thread (japanese) that kinda shows the same thing:https://communities.vmware.com/blogs/yueisu/2013/12/13/vmware-horizon-view%E3%81%A7windows-server%E3%82%92%E4%BB%AE%E6%8…
So to sum up my findings for win2008 as a desktop:
-vcenter managed, manual or auto pool > OK
-unmanaged, manual: NOT OK
-unmanaged terminal > OK
Cam anyone confirm this?
