Hello, I am facing a problem with my sccm 2007 sp2, it was working fine and any new computer join to the domain appear in the all system collection. Now if I join any new computer to the domain, the sccm can't discover it, the old machines are fine. I tried to force the AD system discovery by check on "run full discovery as soon as possible" but with no luck I check the status messages and I found warning message ID 5203 any suggestion? Thanks

Could this be a DNS issue? Please check if the machines in question are correctly registered with DNS. AD System Discovery relies on DNS for Name resolution to contact the machines.Miguel Rodriguez

Thank you for your reply, the machines are correctly registered in the DNS. any other suggestions?

See adsysdis.log.Torsten Meringer | http://www.mssccmfaq.de

I checked it, No errors but there are warnings: WARN: Could not get property (domain) for system (0x80005010) INFO: DDR was written for system

INFO: DDR was written for system Indicates that a data discovery record was written successfully? So the client was discovered successfully. Any chance that there is a backlog in the inbox (\auth\ddm.box)?Torsten Meringer | http://www.mssccmfaq.de

Sorry I didn't get you, what you want me to check?

See http://technet.microsoft.com/en-us/library/bb892790.aspx and check if there are many unprocessed files or in \BAD_DDRs in the inbox I mentioned before.Torsten Meringer | http://www.mssccmfaq.de
