RHCJMO

Problem: Domain account is not allowed to access secondary drives that have been added to a fresh installation.

Troubleshooting:

1) Verified the issue is security related. Cannot browse via cmd to any directories, receive "Access Denied" errors. However, when I run CMD elevated (as admin), or run Server Manager elevated, I can access the drives (via Disk Management with the latter). Also verified domain user is added to the local administrators group. Copy of error:

Also, I was able to access the drive's administrative share remotely using the same account without issue.

2) Manually added domain user to the security permissions of the specific drives with "Full" permissions. Ran "Effective Access" permission analysis which shows the user account in question has full permissions to the drives. Issue persists.

3) Additionally, disabled hot-plug function on drives for VMware.

This issue is also appearing on a new Server 2016 VM. What am I missing here? It seems the system isn't detecting the admin permissions level of the account unless forced to, which is not usual.
