I have a SCCM 2012 R2 infrastructure in place and have been using it for several months. I have noticed a problem with application and package deployments that are targeting device collections. Once the package has been distributed to the various distribution point servers and the distribution shows as successful the deployment state never changes from the grey "unknown" status. Most of the deployments I have done this way are set to run as soon as possible and for the most part I have specified that they run immediately regardless of the maintenance window. I have checked my boundaries several times and have confirmed that everything is set properly (via proper IP address ranges). The thing that perplexes me is that in my effort to get these packages deployed I decided to see if I could instead deploy to users and without any other changes I have been able to rapidly push these items (most of which are .vbs scripts that do things like copy files or create folders on workstations) without fail. The deployments often kick of within a few moments of a forced machine policy evaluation cycle. I am at my wits end to figure out why deployments go smoothly to user collections but seem to get stuck in limbo when device collections are used. I would be happy to provide any pertinent log info that would help in the diagnostic process.
I would like to add that the endpoint protection updates created through the ADR seem to be flowing (or at least the compliance state of workstations would indicate that they are). Also the Software Center and Application Catalog seem to work without any problems.
Thank you in advance for any help you can provide.
V/r,
