I could see that many machines are not showing any data about the VSE installed on the machine, but on the client side I could that the machine are updated with the latest DAT definition. Please find the below screenshot for your reference.
I could also confirm that the "plug-in value" is '0' and not '8'.
In few machines even the agent details is not displayed where it is communicating every 1hour.
Once we reinstall the VSE it starts displaying the details. Can you guys please help me with a solution as re-installing McAfee VSE/agent on 1000+ machines isn't feasible.
Hmmm, not sure on this one - try enabling remote registry/force policy update
