I have a similar problem with an orphaned VM (greyed out).
Restarting of VC 2.0.2 doesn't help.
service mgmt-vmware restart helped me sometimes.
But I have on issue which none of them helped me.
I must migrate all the VM's on that host with vmotion and the reboot the host on which originally the orphaned VM resides.
After the host reboot, the orphaned VM went away. - STRANGE -
