Extra System records

[Config Manager Manager]

So, I have about 2200 actual PC's that I manage, however it shows about 3500 "all systems" PC's with around 1300 Showing "All Systems - No Client".

 

98% of these PC's are not ping-able and show no host found in my RCT Recast tools add-on under ping collection. There are no records in AD for these, as well as DNS. As far as I can tell, I have little to none duplicate GUIDS after running every query under the sun.

 

Has anyone seen such a thing? My discovery is set to only discover PC's that have been logged into within 30 days, same with parameters for the automatic aged removal. DNS scavenging is fairly aggressive.

 

I cannot find where these extra systems are coming from if they don't exist anywhere in the environment or AD. I've deleted these extra Systems in SCCM, and they come back during the weekly Delta discovery, but not in the incremental discovery.

 

I can give more specifics if necessary, but I thought I'd see if anyone else has seen something similar first.

 

Thanks,

It means that all of these computers still exist within AD, I would check AD. It is also easy to see which Discovery method, is adding the record to CMCB. Look at the properties for the computer to see what is adding it to CMCB.

Well, the strange thing is that they don't exist in AD.

 

Today I decided again just to delete every item in SCCM that had no client. I then proceeded to run a full system discovery and came back with only 190 PC's without a client. I'm not sure what changed, whether it was records in the DB that never got truly deleted until now or something else.

 

The entire time my delete aged records for everything has been at 30 days, and my discover systems has been only items logged into in the last 30 days. How we managed to get an extra 1,000+ systems lingering is beyond me.

It the object get recreated then they exist within AD. There is a small chance that your query is the problem but I assume you are using default reports or the console to see the computers.
