Hi All In advance I apologise for my lack of SCCM knowledge. This has been handed over to me while a colleague as gone on sick leave. We have endpoint on our client PC's set to recieve their updates from SCCM. This hasn't been working recently and I don't know why. When I go into Site Status I see the that Software Update Point, Application Catalog Web Service Point & Reporting Services Point are all marked as critical. I have tried reseting counts but that doesnt help. I have attached the errors of Software Update Point. Under Components I have one critical error. This relates to SMS_SITE_SYSTEM_STATUS_SUMMARIZER. Can somebody please point me in the right direction as I honestly haven't a clue. Thanks so much in advance.
