Hi All,I am trying to work out what has gone wrong with my SCE install....On the home screen in SCE I see "33 Computers not contacted in 30 days" - Why is this - I cant find any info on how to troubleshoot SCE when this happens....I really am just getting started with SCE so any pointers would be greatly appreciated.ThanksPaul

Hi,1. Open dsa.msc on server to check whether clients were added in "SCE Managed Computers" group2. Run rsop.msc on clients to check whether the GPOs: SCE Managed Computers Group Policy& System Center Essentials All Computers Policy had been applied correctly on clients.Check that the client is configured to use the SCE server for Windows Updates. The following registry entries should be set to https://<SCEServerFQDN>:8531HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\windows\WindowsUpdate\WUServerHKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\windows\WindowsUpdate\WUStatusServer3. Check whether the required ports for communication between clients and server had been opened, or disable the firewall as a test. 4. Is there a proxy server in your scenario? If not, please ensure there is no proxy setting in IE and run proxycfg -d (netsh winhttp reset proxy in vista)command on problematic SCE clients.5. Run wuauclt /detectnow and reportnow on the SCE agents.HTH.Jie-Feng Ren - MSFT
