Error: Device Control Engine Offline

This error can occur for a variety of reasons. To resolve the issue, follow the instructions below.

For an overview of the Device Control module, see Device Control.

In the Deep Security Manager console, check for other errors on the same machine. If errors exist, there could be other issues that are causing your Device Control engine to be offline, such as communications or agent installation failure.
Check communications from the agent to the Deep Security Relay and Deep Security Manager.
In the Deep Security Manager console, view the details for the agent with the issue. Verify that the policy or setting for Device Control is turned on.
Deactivate and uninstall the agent before reinstalling and re-activating it. See Uninstall Deep Security and Activate the agent for more information.
In the Deep Security Manager console, go to the Updates section for that computer. Verify that the Security Updates are present and current. If not, click Download Security Updates to initiate an update.
Check if there are conflicts with another anti-virus product, such as OfficeScan. If conflicts exist, uninstall the other product and Deep Security Agent, reboot, and reinstall the Deep Security Agent. To remove OfficeScan, see Troubleshooting guide for client and agent manual uninstallation issues in OfficeScan.

Make sure the following services are running:
- Trend Micro Deep Security Agent
- Trend Micro Solution Platform
Check that all the Device Control related drivers are running properly by running the following commands:

For all versions of Deep Security Agent:
- # sc query AMSP
If a driver is not running, restart the Trend Micro services. If it is still not running, continue with the following steps.
Verify the installation method. Only install the MSI, not the ZIP file.
The agent might need to be manually removed and reinstalled. For more information, see Manually uninstalling Deep Security Agent, Relay, and Notifier from Windows
