ferratho Posted April 30, 2014 Report post Posted April 30, 2014 So last spring I rolled out SCCM 2012 and set up the whole boundary group/discovery thing so that it automatically populated my device and user collections based upon Active Directory. All of my computers (app. 750) have been available in SCCM for a year now. All was good - I was interacting with my comptuers and deploying software through SCCM with no issues. Now I'm doing OS re-installs (the OS image does not have the SCCM client pre-installed) on computers. These are computers that were previously known to SCCM, but after restarting them with a fresh version of Windows, the SCCM client software does not get re-deployed to them. I've let them sit for hours, days, even a week. I have Client Push Installation configured for the site with an account that has both rights to the SCCM server as well as local admin rights on each machine. If I browse to that machine in its device collection (where it remains listed), I can right-click it and manually install the client. That works just fine. But I don't want to do that for 750 machines. Can someone please tell me what I'm missing? Thanks! Quote Share this post Link to post Share on other sites More sharing options...
Peter van der Woude Posted April 30, 2014 Report post Posted April 30, 2014 If you didn't remove the device from ConfigMgr (or let the Clear Install Flag task run) the client is probably still listed as YES. This prevents the auto client push from starting. Quote Share this post Link to post Share on other sites More sharing options...
ferratho Posted April 30, 2014 Report post Posted April 30, 2014 Thanks, Peter. So, how do I go about doing that? I have technicians who are out in the field re-imaging computers and I seldom hear about it since it's a fairly automated process that doesn't require an admin to be involved? Is this something that must be done on a per-device basis or is there some sort of client setting that can govern that? Quote Share this post Link to post Share on other sites More sharing options...
ferratho Posted April 30, 2014 Report post Posted April 30, 2014 Technet says that in 2012 "Automatic, site-wide client push now installs the Configuration Manager on existing computer resources if the client is not installed, and not just newly discovered computer resources." Is that done through this flag task run that you mentioned. Microsoft seems to make it sound like it'll just happen once you configure client push.

Peter van der Woude Posted April 30, 2014 Report post Posted April 30, 2014 The Clear Install Flag is a site maintenance task that by default is disabled. So either enable that task (just be sure to read about it first on how it relies on heartbeats), or let your techs communicate about what they're doing.

ferratho Posted April 30, 2014 Report post Posted April 30, 2014 So I see both of those setting areas (heartbeat & clear install flag) but they don't use the same time increments. I've got heartbeat set to two hours but the most frequest I can do for clear install flag is 1 day. Quote Share this post Link to post Share on other sites More sharing options...
Peter van der Woude Posted April 30, 2014 Report post Posted April 30, 2014 That's very aggresive... keep in mind that this would mean that when a device is offline for more than one day for whatever reason it will be marked as NO client. Do note that the next heartbeat will get the client back to YES. Quote Share this post Link to post Share on other sites More sharing options...
ferratho Posted April 30, 2014 Report post Posted April 30, 2014 But that's just it. It's set that way because the reinstall wasn't happening so I felt it clearly wasn't aggressive enough. Yet even with these settings, I'm not getting a client installed after an entire day. Quote Share this post Link to post Share on other sites More sharing options...
Peter van der Woude Posted April 30, 2014 Report post Posted April 30, 2014 Is the clear install flag doing its job and marking clients as NO? Quote Share this post Link to post Share on other sites More sharing options...
ferratho Posted April 30, 2014 Report post Posted April 30, 2014 I don't know that I have a clear answer on that. Is there a way to force the Clear Install Flag maintenance task to run or do I simply have to wait a full day? Quote Share this post Link to post Share on other sites More sharing options...
