Applications are installing, but the deployment statistics are not updating

Hello all,

I'm trying to install a few applications, but we'll use the MBAM Client as an example, as it's small.

I have a couple of VMs and test machines, and can verify that the computers are installing applications from the deployments I set up, but they are not reporting back their status to the deployment statistics. They all just sit there with the Client Check Passed/Active status in the unknown tab.

I can even uninstall the app again, force the Application Deployment Evaluation Cycle, and watch it re-install. Is there something I'm missing, or should be checking?

Thanks,

Rob
