Credential Check Failing. Stumped.

New install of Backup Exec 2012.  I am setting up new backup jobs, but having the credential check failing for Shadow Copy Components only.  The credential check is passing for all other resources such as local disks, utility partition, system state, etc.

I am using an active directory user account as the System Logon Account.

This AD account is a member of Domain Admins.

On each server with a remote agent the account is also a member of the local admins and local backup operators.  The remote agents are all running as Local System.

In my Default Domain GPO, I have added the following rights for this AD account:

Act as part of the operating system
allow logon locally
Backup files and directories
Create a token object
Logon as a batch job (Windows 2008 only)
Logon as a service
Manage auditing and security log
Restore files and directories
Take ownership of files and other objects

And I have made sure it is NOT added under:

Deny logon as a service
Deny logon as a batch

I have re-entered the username and password several times in the BE Logon Account Management.

I have even deleted the AD user account completely (in active directory users and computers), and re-created it.  Though with the same name as before...

I have even tried using my own enterprise admin account as the System Logon Account as a test, and still get the same credential check failing only on Shadow Copy Components.

I have exhausted all the support forums and articles via Google.  I don't know what else to try.  Any advice would be greatly appreciated.  TIA!
