July 26, 2016 - ConfigMgr/SCCM, Deployment, System Center

this is probably in the TOP 5 of OSD issues around there (no matter which version of SCCM you are using)

I have assembled the following causes, if you have more please comment so we can update the list guys (and girls…) !

– The computer is not imported in the console if you are using known computers not unknown computers

– If you are using unknown computers, delete any devices with the name unknown (but whatever you do DO NOT delete the two builtin unknown records)

– Make sure that the TS is enabled

– Make sure the device is in a collection with a TS deployed to it

– Change the schedule of the deployment to yesterday

– Check if the TS deployment is set to ‘configmgr client, media and PXE’

– The computer is imported with a mac address that is already in the database (check the report ‘MAC computers for a specific mac address’

– The computer still has a cached pxe advertisement

– The computer is in the console but is not approved

– The computer has incorrect date/time settings

– Check if the DP certificates have not expired

– The bootimage associated to the ts has not been distributed yet

– The resourceid of the computer that boots is already used by another machine in the console (verify the ‘itemkey’ value from SMSPXE.log versus the result from select * from v_R_system where resourceid=’….’

– The biosguid of the computer that boots is already used by another machine in the console (check the biosguid from SMSPXE.LOG versus the result from select * from v_R_system where smbios_guid0 LIKE ‘%…%’ (try with a part of the biosguid…)

– Delete the device from the console and import it again

– Check if there are any bad policy assignments in the sql db:

SELECT * FROM ResPolicyMap WHERE machineid = 0 and PADBID IN (SELECT PADBID FROM PolicyAssignment WHERE BodyHash IS NULL) if this returns anything then you have to delete the items with: Delete FROM ResPolicyMap WHERE machineid = 0 and PADBID IN (SELECT PADBID FROM PolicyAssignment WHERE BodyHash IS NULL)
