Hello There...

I think i got my self in big trouble... I had a messed up collection with workstation servers and obsolet clients... so i deleted all machines in "All Systems" collection and as i know it should be automatically re-populated... and in fact it does... now is almos 100% populated...

But when i open ConfigMGR console, NONE of the machines in "All System" collection appears to have SCCM Clients :(... so i dont know should i wait more.... for clients field to appear "YES"

Thank's guys.

Yes, just wait longer. The problem with deleting all of those resources is that now all of the hardware and software inventory that was in SCCM is now gone. So it has to do a resync. So you'll have to wait until hardware and software inventory run again to get all of that data back.

So help us understand why you thought you needed to delete all systems? Just because a collection has workstations, servers and obsolete clients doesn't mean you need to delete all data from SCCM. It just means you may need to change the configuration of that collection. SMS & SCCM are always going to have obsolete, decommissioned or non-client records in them. It's just something you have to accept. But that doesn't mean they have to be in all of your collections. If you write your collection queries so you exclude the stuff you don't want and if you've got the maintenance tasks turned on to delete obsolete data, then they should get excluded and cleaned up properly.

Thanks guys.

Well actually i deleted so..:) i have to deal with it... but it really became a mess around here, also with HW/SW Reports, and other stuff. so i just want to wipe away all of it, and start from the begining, but all i want it to save is... Clients installed on workstation,

Now almost all workstation are populated, but none of them is saying that has a client installed. :( i dont know how long should i wait until all the workstation appear in configmgr console and saying that client is installed...

Regards,
Ridvan

Could be hours. As machines send inventory deltas, the server will realize it can't write the delta to the DB because the inventory doesn't exist anymore. At that point it will tell the clients that they need to send a full inventory again. So however long it takes for your clients to wake up for their next inventory cycle.

John,

I have never investigated this thoroughly. I know the information does come back eventually, but I was wondering if you could elaborate? I think what your saying is that the next time a client sends its H\W the server will issue the resync instruction in the next client policy. Then, the client will generate a new 100% inventory. So, Ridvan could look at his H\W inventory and Computer Client policy schedules to get a rough idea.

For example, assume the client polls every 12 hours at 6:00 AM and 6:00 PM and the H\W inventory is scheduled daily at 6:00 AM. His worst case for computers that are on-line would look something like this:

The first post-delete H\W inventory goes up at 6:00 AM (every 24 hours).
The server detects the discrepancy and updates server side policy.
No later than 12 hours later, the client policy should have detected the policy update requesting the 100% inventory.

So in this example, no later than 6:00 PM, the client knows to send a 100% inventory. Then, does the client immediately exectue the inventory or does it wait until the next 6:00 AM inventory reporting cycle?

Hmm, well I always assumed that inventory was initiated with the next policy and sent as soon as it's done, but now that you mention it, I'm not 100% sure if it does that or waits until next inventory cycle. But either way that's the worst case scenario, the next inventory cycle.

Dears... Its been 4 Days that i deleted all resources and untl now i get back only 260 Clients, and i have almost 1k of workstation that i am 100% sure that has client installed on it... but runing reports from these 260 computers is 100% true. All HW/SW Reports are correct !.

H/W & S/W Inventory Cycle is set to be run everyday,
under Tasks/ "Delete Aged Inventory History is set to 6 days, (the reason why i set this it was because i saw in reports a old computer that had been removed from our office long time ago, and report for that sitll exists.

Ridvan

Having the "Delete Aged Inventory History" setting is way too low. You will only retain data for 6 days. So if you have a system that is offline for more than 6 days it is removed from the site. To tackle why non-existant systems are still populating your site you would need to look into what is keeping them around. This is can usually be attributed to several things, existing DNS/WINS/DHCP entry, system is still in AD, the system could still actually be around (it does happen, but usually more in a large environment).

You should set the number to something where you can maintain a good amount of history for reporting. Otherwise, your systems will continue to pop-in and out of the site for the upcoming days.

The 260 client number is this the actual number of clients that are showing assigned, correct? What are you seeing for the number of records discovered? Is that number close to what you should be seeing? Discovery should have repopulated most of your site with unassigned clients.

You might also want to check and see if you are having a large number of orphans (hardware/software). You also might want to check and see if you are having any kind of inventory processing backlogs or issues. I have had a site that was completely rebuild from scratch with the exact same build information repopulate most of the client in just a few days, so it is possible to repopulate deleted resources without any issues.

Yes exactly ! Discovery obtained all clients, bu most of them unassigned, until now the number of assigned clients achieved 300, (totall number of assigned & Unassigned, clients is around 1 thausand.)

Hmm this is delicated issue, i think it should exist a way, that SCCM will operate independetly from DNS/WINS/DHCP, it should do a reports based on their assigned clinets, not based on computers that are listed in DNS... (I mean its ok when it discovers the client, to do that from DNS/DHCP or Wins, but when it cames to report, it should operate only based on assigned clients of SCCM)

yes i had alot of orphans HW/SW reports, and that was a reason that i deleted all resources, and strated all over!

If you have machines listed as discovered, but they do not show as assigned, that suggests to me that there is an error in your site boundaries.

You could modify your reports, if you like, to only show systems whose hardware inventory date is 6 r fewer days old. I do this on a few of my reports.

Hi There,

Actually, this is not the problem, because i just discovered today that number of assigned client is growd to 350, so i think day by day, all clients would be assigned automatically,

IT sounds nice, but where is that option to do that ?!

At what frequency do you have your heartbeat and HW/SW inventory set too? This seems to be taking longer then I would expect.

It should be set to what you want in your environment. With systems reporting inventory once a week and your delete aged history inventory set to 6 days, I wonder how you even have any clients in your site. How often does the heartbeat discovery run?
