Hello,
The Domains node contains two sub-nodes: Active Directory Domains and Microsoft Windows Network. The Microsoft Windows Network node enables you to browse to resources in a Microsoft Windows network.
The Active Directory Domains node enables you to browse Active Directory domains.
Backup Exec automatically discovers the Active Directory domain to which the media server belongs and displays it in the backup selection list. Also, you can manually add Active Directory domains to the backup selections list.
You cannot select the Active Directory Domains node itself for backup. You must expand the node to browse Active Directory domains.
When you add an Active Directory domain, you must use a fully qualified domain name.
Thank You,
Shweta
