EMC VNXe 3300 Shared folders issue

Hi everyone,

yesterday I noticed that I can't access my CIFS shared folders. It's asking me for a user and password but whatever I type is incorrect but it shouldn't be.

Connecting through computer management also says I don't have permission (I'm the domain admin).

I have admin access to the EMC Unisphere and access with the service account through SSH. I tried rebooting the system, re-imageing and re-adding the shared folder server to the domain. I also tried enabling NFS but same issue with no permissions. Nothing helped, it's like the share permissions are lost.

The only thing I need is to recover the files from some of the shared folders. Is there any way to access the files?
