We currently have SCCM collections that query Active Directory OU's. These have been working fine until we recently had a restructure of our AD OU's. I have edited the Querys to reflect the new OU value's which SCCM is picking up. However, some OU's are missing PCs E.G. We have a Laptops OU that has 37 PCs in Active Directory but the SCCM query (below) is only pulling through 22 PCs? select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System where SMS_R_System.SystemOUName = "******.GOV.UK/COUNCIL STAFF/FINANCE AND RESOURCES/ICT - CT/LAPTOPS" Further to this, when selecting the OU values the deleted AD OU's are still listed in SCCM E.G. The query above points to the FINANCE AND RESOURCES Department but the old value which was '4 Finance and Resources' is still listed. I have re-run 'Run full discovery as soon a possible' within Active Directory System Group Discovery but this has not rectified the problem. I have reviewed the posts on here and googled this until i'm blue in the face but don't seem to be getting anywhere. Has anyone experienced this or have a suggestion on how to resolve it?

The old value will be listed as long as this discovery information is in the database. Have you pointed AD system group discovery to the OU(s) where the computer accounts reside?Torsten Meringer | http://www.mssccmfaq.de

Thanks for that Torsten. This is how our ADSGD looks: It links to the top level of our domain, this is what it has always been. Should I re-point it back to the domain? Cheers, Jon
