Yes, full Admin rights on PC, happens with all profiles, profiles are not corrupted. All Admin users that log on...
oh yes, re-installed the vSphere Client, on 5.5 now, and still the same, after every new client comes out, we uninstall and re-install in hope one day, it will be fixed.
I seemed to remember ths happened after a bunch of Windows updates, a long time ago, we use vSphere Client remotely now, and it's going away now with 5.5./Web Client....
thanks for trying, many VMware Admins have spent many hours over the years, in their "spare time" trying to fix, with no solution yet!
One day the PC will be retired, but not yet..
