    SCCM 2012 PC discovery problem

    We have recently installed new SCCM 2012 with SQL 2012. After installing SCCM 2012 successfully it discovered only 40 machines instantly and all the users( 2505 ) in AD.

    We are unable to discover any other machine since the first discovery ( 40 PCs only ).

    All discovery methods are enabled.

    Anybody has the same issue or already resolved it before. We have also checked the system discovery logs.

    Please help to resolve the issue.

    Why are you using all methods? Do you need them all? Ideally just turn on AD discovery. Select the OU you want to discover and all is good to go.

    In Devices on a discovered machine, right click one and properties, what method was used to discover it?

    How have you setup you boundaries and boundary groups?

    How long have you left it to discover?

    As above, you should only really enable AD discovery. Benefit to that is that it only picks up machines you want it to so it can be limited to certain OUs or AD sites. Install everything and you'll end up with performance issues with it polling just about every part of your network every (however often you've set it). Especially heartbeat discovery, although that requires the client to be already installed. Have you clicked "run discovery now" and left it for half hour or so?

    We enable system discovery initially but unable to discover machines so had to enabled all methods.

    We have setup boundaries correctly.

    its been few weeks now.............and still waiting..... all the services in SCCM 2012 are also running ..........

    Thats not advised. You need an account that has read only rights. A standard Domain User will do the trick.

    Once all my PCs are discovered I will setup a standard domain user for this purpose which is always the best.

    Thank for pointing out..

    In Devices on a discovered machine, right click one and properties, what method was used to discover it?

    Agent Name: SMS_AD_SYSTEM_DISCOVERY_AGENT

    All I checked are discovered with above discovery method

    How have you setup you boundaries and boundary groups?
    Desktop Range
    ip subnet
    172.16.0.0 ( which is our internal IP range )

    Boundaries and Boundary Groups are vital in SCCM 2012 - without them yo will get a lot of unexpected results!

    In SCCM 2012 Console - Goto Administration -> Overview -> Hierarchy -> Boundaries.. Create a new Boundary (I use my AD Site (EG DEFAULT-SITE-NAME)
    Then, In Administration -> Overview -> Hierarchy -> Boundary Groups .. Create a New Group (EG "My Boundary Group") and and your Boundary or Boundaries to it
