unable to connect to the service in Backup Exec 2012

Hi all,

I have problems about the logon account in Backup Exec 2012.

My scenario:

One AD Domanin Controller "Test.com", one Backup Server "BKServer"

I create a AD account "operator" and add this to Backup Operator Group.

I also add Backup Operator to the Group Policy Management Console at the domain controller and  Local Security Policy on the Backup Server "BKServer"

·               Act as part of the operating system  

·               Backup files and directories

·               Create a token object

·               Log on as a batch job Log on as a service 

·               Manage auditing and security log (BE 2010 R3 and later)

·               Restore files and directories

·               Take ownership of files and other objects

In BackUp Exec 2012, i create a "Test\operator" logon account, for the system logon account is "Test\Administrator", both is common.

When i use AD "Administrator" system account, i can logon to both "Test\operator" and "Test\Administrator" in BE2012.

When i user AD "operator" system account i can only logon to "Test\Administrator" in BE2012, but not the "Test\operator" account. A message shows that "Unable to Connect to the Service"

Please help!!
