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,
