A customer implemented an EMC Data Domain system in a Microsoft Windows environment two
months ago. The Data Domain system was added to the Active Directory domain and backups ran

normally until now. The backup administrator is trying to access the CIFS share on the Data
Domain system from the Windows storage node and is getting an access denied message.
What is a possible cause?

A.
Data Domain system should be reconfigured for Active Directory support

B.
Time on the Data Domain system is more than five minutes apart from the Active Directory
server

C.
Replication services on the Data Domain system are stopped

D.
Cleaning activities have been pending on the Data Domain system for more than one week
