Ok, so I'm banging my head on a desk right now, because I know it should work but it doesn't.
I have a simple folder on Server 2012. I've set the permissions to Full for Domain Admins and Owner Domain Admins. I'm obviously a Domain Admin. I also have a clients Security Group set to full permissions. I've also added a share for both Domain Admins and Client SG. I'm able to open an browse the folder while looking at it as a share, however locally I'm getting a You don't currently have permission to access this folder.
Please help me, I'm starting to feel like a newbie.
