Then a discovery can be run which will bring back only the active systems in the collection.
Once the agent is available on the network and the client is installed, the client goes through the following actions as part of the reporting process: So only if this process is completed and it continues to happen will the client remain reporting to the server.
If yes then first restart the system and then initiate the discovery cycle from the control panel agent properties action TAB.
Stale Entries: When you use AD discovery, the DDRs are created for the computers that reside in the AD container that we have requested to be queried by the discovery process.
There is a Maintenance task that will clear the inactive records but if the discovery process runs again and the AD container still has these entries then they will simply show up again.Sometimes the most challenging part of the Configuration Manager 2007/SMS 2003 deployment phase can be ensuring that the client successfully reports to the site server.We occasionally see these issues here in support, typically either as cases for clients not reporting after the client installation, or maybe where it’s noticed that the client count is decreasing from the collection.For that you will need to check the mpcontol (Log location: \SMS\logs in SMS and \program files\Microsoft Configuration Manager\logs in SCCM).If it is showing a 200 OK status code then that means the MP is working.If you suspect your clients may have multiple GUIDs refer to https://technet.microsoft.com/en-us/library/cc917513for information on how to resolve the issue.MP not working as a result of which the policies are not getting downloaded You first need to check to see whether the MP is working.There are various reasons why a client may not be able to report to even if the SMS\SCCM agent is installed on a machine.A few of these reasons are discussed below: The first thing to check is whether the client is on the network, and if it’s not on the network, does the system even exist?Unable to get the site code If the client is not able to get the site code, you need to check first the boundaries as above, and also verify that the site information is published in the AD.You can check the last part of the after you start the site component manager which will say that the components like the MP, SLP etc successfully published or updated.
