VM BUG = "Object reference not set to an instance of an object"

I have two users that when they revert from a snapshot and it powers off when they go to power it back on they receive an “Object reference not set to an instance of an object.”. They will then call the IT dept to manually power them back on and it comes up fine.

Any ideas?

Thanks in advance!!!

Permissioning in VC is one of the most FUBARed things in all of VI-3. The implementation of an authentication/authorization system that coincides with what most VC users understand (i.e. Active Directory) would be a very good thing[/i]

Just a straggling post to this thread... I also saw this same error message numerous times during my efforts to modify the default permissions. I was attempting to create a local group on the VC server called VIadmins, and place the appropriate domain user group into that local user group. I then granted the VIadmins group administrator rights on the datacenters within VC. The problem came about when i removed the local Windows Administrators group from the VC administrators of the Virtual Infrastructure.

FYI - Just had this problem today when trying to right click and remove an invalid VM. The resolution was to disable the virtual infastructure client plugins. After I removed the VM from inventory I was able to re-enable the plugins.
