some agents are showing in state tab "not monitoring" and some windows operating system tab is showing "not monitoring" but state is showing healthy, could now understand why this is happening?Sharad Singh | My blogs: SharadTech | Twitter: @MrLucknowWale |

Hello! Are the DNS configurations ok for the servers in the state "Not monitored"? See this thread: http://social.technet.microsoft.com/Forums/en-US/operationsmanagergeneral/thread/d315f7b5-ebc3-4285-b0b8-04aaa75d8b4c/ Markus Blske, Lumagate. www.lumagate.se Blog: www.opsmanager.se|www.scdpm.se

Hi, The ones that show Not monitored in the state tab might be computers discovered through an agent with the proxy enabled. In many cases these are machines that belong to a cluster, or domain controlers in another site. For the not monitored in the Windows Operating System tab: please make sure the relevant MP for that OS is up to date. Otherwise check out this this KB article: http://support.microsoft.com/kb/979387 Hope this helps,

Hi Markus, DNS configuration is ok, HI Marthijn yes those 3 servers are domain controllers but health state is showing healthy but in windows operating system they are not monitoring even all needed MP have been imported, because some others are showing healthy Sharad Singh | My blogs: SharadTech | Twitter: @MrLucknowWale |

Hi If they are domain controllers then make sure you have run HSLockdown to allow the agent to function. http://thoughtsonopsmgr.blogspot.com/2009/09/hslockdown-explained.html Cheers GrahamNew SCOM 2012 Blog! - http://www.systemcentersolutions.com/blog/ View OpsMgr tips and tricks at http://systemcentersolutions.wordpress.com/
