Thx, but we have already tried that.
The problem is that the root catalog aka the share has everyone Full Control. 2 of the catalogs under that root catalog also has everyone Full Control, but the third catalogs only has System as user. We have tried making a new share which points to the catalog directly with everyone Full Controll but we can't access it from windows, it doesn't get thoose rights.
For information theese are snapvaults from another domain, so those users don't follow.
I'm guessing thas user System has no known password, otherwise one could connect as that user and add user everyone and/or administrator?
My thoughts now is that maybe the only thing is to break the relationship and make a new qtree to snapvault to, and a new share of course.
