Hi All!
I've renamed the vCenter server and when logging into the vsphere web client a warning pops up with 'Could not connect to one or more vCenter Server systems'.
I have un-installed vCenter and re-installed, removed the old SSO certificates which allowed me to connect into the vCenter server.
Everything is now functional however I get this warning it is attempting to connect to the old hostname.
Any ideas I can unregister the old name?
Worst case I can un-install all the vmware components and start fresh, however I'd like to avoid that where possible 
Thanks!
