The Carbon Black Support Team has reached out and state they detected duplicate SID's reporting into CDC
Environment
App Control Server: All Supported Versions
Microsoft Windows Server: All Supported Versions
Cause
Multiple App Control Servers sharing the same SID, often as a result of cloning a Server. Each Server must have its own unique "ParityCenterSIDHash". Each Reputation Key is associated with a Service License. The combination of these generates a unique Server ID.
Resolution
Use SQL Server Management Studio as the Carbon Black Service Account and execute the following query for each Server:
use DAS;
SELECT name, value FROM dbo.shepherd_configs (nolock) WHERE name in ('ParityServerVersion', 'ActivationState', 'ActivationVerified', 'ActivationKey', 'ParityCenterSIDHash');
Each Server should have its own unique "ParityCenterSIDHash". If 2 (or more) servers have the same SID, do the steps below on each duplicated server. (If there is only one server, do the same steps on just the one).
Reset the Server ID for each duplicated Server. (Not needed on the original Server)
