Have a domain account and a local account. Both are administrators -- they are part of the administrators group. For some odd reason, something must have gotten corrupted as accounts require elevated privileges to edit or rename existing files and I can no longer create any files in any directory. I only can create "New Folder" and create files within that folder. The expectation is the Owner of the file or folder should be the administrators group when creating a new folder or file. Instead, the owner is me. And existing files do have Owner as administrators group.
I don't know if there's some corruption with the administrators group or domain and local user accounts. As a test, I tried remapping permissions for one folder and set the Owner as administrator group and issue did not resolve. If I set the Owner to myself and include myself in the permission list, however, then it's fine and I can create and edit files freely.
UAC is off. Slide bar is at the very bottom. I ran SFC /scannow and logs showed numerous duplicate permissions messages but not for every folder in the system. I don't see any GPOs configured. I ran DISM and component health is good. Nothing to repair there. Only thing that comes to mind is firewall and anti-virus. Windows Firewall is off.
Rebuilding this server is a last resort. Would like to avoid that use case.
Any ideas on what could be wrong and how to fix?
