Like the title tells, my All Systems collection doesn't update anymore. I have a new pc's in my domain but they arn't displayed in system center. I deleted the collection and recreated it but that doesn't work either. How I can solve this?

Did you enable any Discovery methods ? if so ,check the discovery log files from site server if server is able to resolve the computer names from AD. are you in SCCM 2007 or SCCM 2012 ? if you are in SCCM 2012,Please use connect.microsoft.com for ConfigMgr 2012 beta questions. //Eswar Koneti @ www.eskonr.com

Is there anything useful in colleval.log? Does the "all systems" collection contain any members at all? How does the WQL query look like?Torsten Meringer | http://www.mssccmfaq.de

Did you delete All Systems? Check the colleval.log file on the site server and see if collections are being updated.Kent Agerlund | My blogs: http://blog.coretech.dk/author/kea/ and http://scug.dk/ | Twitter @Agerlund | Linkedin: /kentagerlund

BTW I hope you didn't delete the "All Systems" collection, that is a special collection with a special ID. the only way to get it back correctly is to re-install a service pack. If you did re-create the "All Systems" collection, delete it and re-apply the service pack. http://www.enhansoft.com/

I gaved the pc's a new computer name and the problem was solved. Strange but true.
