Hi!

I have come across an interresting problem that I really need some help with. In our environment, for some unknown reason computer objects in SCCM 2007 SP2 disappears randomly from the console. It can happen to computers that have been in the system for a couple of weeks and months but also to computer objects created just yesterday. I first noticed this on a computer where RAP was totaly greyed out. So I trigged some actions in Config Manager client but nothing happend. Checked the execmgr.log file and it showed me that all policies was deleted. Hmm...Then I uninstalled and reinstalled the SCCM client (ver 4.00 SP2) but that didn´t help either. Ok, I then tried to rebuild the machine but discovered that I couldn´t PXE boot anymore. So I checked the collection to where the OSD TS is advertised and found out the the computer object was missing in the collection. Completly gone. Couldn´t even find it in "All Systems" on the primary server the client "belongs to". Can´t remember if the computer object was still present in the "All Systems" on the central site but I will check that further (I have created some dummy objects that I´m keeping an eye on...). So how can this happen?

I have checked the maintanence tasks to see if one of those are the reason for this but it doesn´t seem like that. There is no task set to delete anything just after one or two days.

I´m wondering if anyone has seen this behaviour before? And is there a log file that records computer object deletion (both manually deletion and system deletion) or some kind of system status that I can check?

Thanks /Niclas

Even if it gets deleted from a maintenance task a heartbeat should put it back.

 

Systems "randomly" disappearing in ConfigMgr are almost always due to an administrator deleting them. This is usually the case junior admins who don't know how to remove systems from a collection and they delete them instead. There are other ways to "accidentally" delete them also.

There is a query under 'System Status, Site Status, Status Message Queries, Collection Member Resources manually deleted' that will show you any manually deleted records. Maybe check there.

Thanks for quick the response!

Well, yes it should but this also happens to pre-staged computer accounts where the OS hasen´t been installed yet and even to dummy objects. We pre-stage machines (puting a ddr record on the primary server, creating the account in AD and so on...) and 2-3 days may pass before the field technicians install the OS. But then the account has in some cases disappeard.

There is no junior admin deleting accounts. I know that for sure.

I have also, as Danny suggests, checked the status query but there are no entries there indicating that these specific accounts I´m looking for has been deleted manually.

Any other ideas?  =)

Thanks! /Niclas

Hi I'm also facing the same issue. The computer objects get reduced In sccm console . We have 23 primary servers under central. I ran the report of collection member resource manually deleted . No details was found. I even checked in-active clients which is disabled. When we run heartbeat discovery the objects are getting restored. However just to know how it get disappears. Is there any chance of deleting files in DDR inbox under auth folder. Or any other reason. Thanks Krishna

Hi, I have a same problem. I have only one site with one management server. Now computer object disappear from console. After I restart SMS_EXECUTE service, they will slowly return, but only to dynamic collection. I dont know why it is happend. Any idea why it is happend? How can I prevent it to happend again?

Thank

Martin
