Grr run into this before, you create a new folder, give it a new name and somehow your cluster thinks, nah we already have that in there. I double and triple checked ‘Share and Storage Management’, there was no shared folder like that for sure.
Well, good ‘ol regedit to the rescue.
And indeed, for some odd reason, there was a key with that name in there.
If you find a share that doesn’t belong, you can delete the key for the share on all nodes.
