As the administrator, you may have used Custom Grouping in OfficeScan to map all the clients to their domains. However, when you replicated part of the AD structure, only the sub-domains got copied, and not the root OU.
The following has been configured:
Active Directory integration - Administration > Active Directory > Active Directory Integration Custom Grouping > Networked Computers > Client Group > Custom Client Groups
Under the Active Directory Source, the following appears as example:
- Virtual Machines
- Human Resources
Selecting to copy the entire AD structure and selecting "Duplicate Active Directory structure into the OfficeScan client tree" will show all the root OUs and subOUs under the OfficeScan client tree in Client Management.
If you choose to copy only part of the AD structure by selecting some OUs, it is observed that the root OU will not be copied over. The only OU that will be copied are the sub-items of the OU selected. If you use the example above and select the Sales and Virtual Machines OU only, it will copy the following domains into the OfficeScan client tree:
Note: Sales and Virtual Machines OU will not be copied.
