My fileserver running Windows Server 2008 has two logical drives; the C: drive contains all of the system and application data, and the D: drive contains all of the business data. There are several shares on the top level of the D: drive that are working fine. However...

When logged into the fileserver interactively via Remote Desktop, only the Domain Administrator and local Administrator accounts can browse the D: drive. I set up an account called "Maintenance" and added it to the local Administrators group, but when logged in with this user, I can't browse into the D: drive. The D: drive has the following permissions ACL:

Full Access - SYSTEM
Full Access - MACHINE\Administrators

It won't even let me view the ACL for the E: drive. So I tried taking ownership of the E: drive, then I can read the ACL, and "Effective Permissions" says that I have full access. But I still get this error message.

Location is not available
D:\ is not accessible.
Access is denied.

Here's a screenshot proving that I get access denied even when I have Full Access.
