How to remove the Null Entries from SCCM

  • Run this query select SYS1.ResourceID,SYS1.ResourceType,SYS1.Name,SYS1.SMSUniqueIdentifier,SYS1.ResourceDomainORWorkgroup,SYS1.Client from SMS_R_System as sys1 inner join SMS_R_System as sys2 on sys2.NetbiosName = sys1.NetbiosName where (sys1.ResourceId < sys2.ResourceId) to find system with null entries
  • Run this query Select R.ResourceID,R.ResourceType,R.Name,R.SMSUniqueIdentifier,R.ResourceDomainORWorkgroup,R.Client from SMS_R_System as r full join SMS_R_System as s1 on s1.ResourceId = r.ResourceId full join SMS_R_System as s2 on s2.Name = s1.Name where s1.Name = s2.Name and s1.ResourceId != s2.ResourceId and R.Client = null to find system with Null Entries in the console having properties with values "blocked=Null,Client Type=Null,Obsolete=Null,Active=Null" moreover their Hardware id Null System UUID is null and SMS unique identifier is null.

Resolution: These are not obsolete clients, they are what we call “timing issue records” this happens when a PC registers in AD and AD discovery find them before the same PC submits its data to the MP. Really your only option is the delete the AD discovery record ones.

SoYou cannot vote on your own post stretch the AD discovery time to 1 day, That probably can make a difference.

Enterprise CA option is greyed out / unavailable

Many times, when installing Active Directory Certificate Services they cannot choose to install Enterprise Certification Authority, because it’s unavailable as in following picture: Well, you need to fulfill basic requirements: Server machine has to be a member server (domain joined). You can run an Enterprise CA on the Standard, Enterprise, or Data Center Windows Edition. The difference is the number of ADCS features and components that can be enabled. To get full functionality, you need to run on Enterprise or Data Center Windows Server 2008 /12/R2/ Editions.  In order to install an Enterprise CA, you must be a member of either Enterprise Admins or Domain Admins in the forest root domain (either directly or through a group nesting). If issue still persists, there is probably a problem with getting correct credentials of your account. There are many thing that can cause it (network blockage, domain settings, server configuration, and other issues). In al...

Rearm the Office 2013 installation

Image
There is a 25-day grace period from the time of installation of Key Management Service (KMS) clients before notifications to activate are displayed to the user. If you want to deploy an image, you must rearm your Office 2013 installation before you capture the image. If you do not rearm, users see notification dialog boxes at the time that the image is deployed, instead of 25 days after deployment. The 25-day grace period gives ample time for a KMS host to be found and activation to succeed. If activation is successful, users do not see notifications to activate. Rearm the Office installation Rearming does the following important tasks: Resets the grace timer to 30 days. Freezes the grace timer until either an Office application is run, or the ospp.vbs script is run. Resets the client computer ID (CMID). This is important because the KMS host uses the CMID to determine the num...

However, i have discovered these errors on MP: MP has rejected registration request due to failure in client certificate (Subject Name: ) chain validation. If this is a valid client ,  Even though Newly imaged machines are getting SCCM client installed but won't see all the client cycle under 'Actions tab' and also  'client certificate shows "None".  The operating system reported error 2148204809: A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider.  Solution:- Register  new Certificate of Root CA    under SCCM20...
