Ok, so a long time ago on my DD690 pre-boost and post a DL3D I was a newbee and setup a subfolder in the CIFS /backup folder. I created a user ID on my networker server which was a admin and mounted the share and used it for networker backups. Due to business reasons I needed to hold on to these backups for way to long. Anyway fast forward and now I'm on a DD2500(and for several years now on boost) which EMC helped me migrate too. So here's what I think my problem is. Because I was using workgroup permissions and when the migrated I believe the SID under the folder changed. The reason I believe this is when I mount the folder on the old server or anything else I see that dreadful SID and Account unknown instead of the user ID as the owner. And I believe because of that I am simply unable to change the permissions to allow me to delete or remove anything. I simply really want to delete the subfolder /backup/nw and it's subfolders from my datadomain. I'm about to open a ticket with EMC but I figured I would throw it out to you all first.
I am already connecting to the share as a "Admin", and I have already attempted to change the permissions multiple times.
