Doesn't sound like a vCenter issue then. The solution sounds out of my league and would be a support call.
On a side note, I'm getting conflicting information on the vCenter Appliance. It seems like the direction VMware would like you to go. I tried it with my new vSAN, and it was a train wreck. Services would stop, it would crash, errors in the VIC, errors in the Web Client, etc... Every time I called up support they would help, of course, but each tech said they hated working on it and would like to see the Windows version. Then I read Mr. Lam (virtuallyGhetto), and he loves it.
I ended up replacing the appliance with the Windows version and have had no issues since. Thank you, Zach.
