Environment

Cause

A deleted Policy with an identical name still exists and is referenced by one or more Agents or other tables in the database.

Resolution

Manually rename the deleted Policy in the das database.

1. Take a full database backup.
2. Temporarily stop the App Control Server and App Control Reporter services.
3. Run SQL Server Management Studio as the Carbon Black Service Account.
4. Execute the following query to confirm the presence of a Deleted Policy with an identical name, example: Desktops - HE

   use das;
   SELECT host_group_id, name, date_modified, deleted FROM dbo.host_groups (NOLOCK) WHERE name LIKE '%Desktops - HE%' AND deleted = 1;

5. Note the relevant host_group_id and specify it accordingly, example: 16

   use das;
   update dbo.host_groups set name = 'Desktops - HE DELETED' where host_group_id = 16;

6. Execute the query from Step 4 to confirm the Policy's name has changed.
7. Start the Server and Reporter services.
8. Log in to the Console and attempt to change the Policy's name once more.
