Hi all, my question specifically is: Why can I not mount VHDX files using a secondary domain administrator account? The specifics are below.

(Server 1) Domain Controller - Server 2016
(Server 2) RDS 1 of 2 - Server 2016
(Server 3) RDS 2 of 2 - Server 2016
User Profile Disks are housed on Server 1

I am trying to lock down the built-in Domain Administrator account so my staff cannot use it, instead using their own Domain Admin accounts (ex. Admin1). When doing this, however, I now get Access Denied errors when attempting to mount VHDX files on Server 1.

The VHDX actually does mount, but I still get an Access Denied error from these extra domain administrator accounts when attempting to mount and then attempting to enter the virtual disk.

The VHDX files security includes the Domain Admins group w/ Full Control, which Admin1 is apart of. When mounted, the virtual disk has the security group Administrators listed as Full Control; again Admin1 is also apart of this group.

Domain Users have no problems using their VHDX files, but I just can't seem to figure out how to give the additional domain admin accounts access.

We had issues in the past trying to do Exchange CU's with auxiliary admin accounts and I was wondering if maybe that was the problem here.

I am not seeing anything in the Administration, Security, or Application logs related to the access denied dialog box.


Any help would be appreciated, I am on a solid 20 hours working on this. A reboot after work hours did not resolve the issue unfortunately.
