Exchange 2010 - Persistent topology Event 2116 warnings with a Windows 2012 DC RRS feed

  • Question

  • Hi All,

    Ever since introducing a new windows 2012 DC to my environment I have been receiving the below warning event in the application log of my exchange (2010) server:

    Log Name:      Application

    Source:        MSExchange ADAccess
    Date:          28/08/2014 23:58:19
    Event ID:      2116
    Task Category: Topology
    Level:         Warning
    Keywords:      Classic
    User:          N/A
    Computer:      my2012DC.mydomain.com
    Description:
    Process MSEXCHANGEADTOPOLOGYSERVICE.EXE (PID=2688). The domain controller my2012DC.mydomain.com is running Windows (Unknown Operating System) (Unknown Service Pack). Exchange Active Directory Provider requires that domain controllers are running Windows Server 2003 Service Pack 1 or later versions of Windows.

    Event Xml:
    <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">
      <System>
        <Provider Name="MSExchange ADAccess" />

        <Data>(Unknown Operating System)</Data>
        <Data>(Unknown Service Pack)</Data>
      </EventData>
    </Event>

    Normally this would be pretty self explanitory, however, we aren't running anything older than server 2003 anywhere on the network and that particular box is running windows server 2012 standard.

    My 2012 server is a DC but does nothing else and is running in headless mode (no gui) it's off site so we're using a site to site VPN between 2 bits of cisco kit to communicate with it. As far as I know this isn't causing any issues other than clogging up my event log but I'd like to get rid of it in case I miss something important in the heaps (one every 15 minutes) of events this is generating.

    Googling around has raised some points, such as permissions errors (http://social.technet.microsoft.com/Forums/office/en-US/ca9a5803-99bc-4208-b09d-af9a9adfb3df/event-id-2116-category-topology-process-storeexe-pid304?forum=winservergen) however I can confirm that this is not the case for me.

    Does anybody have any ideas why I'm receiving this warning? how does the Exchange topology service determine the OS of it's DC's?

    Any help would be greatly appreciated, many thanks in advance.

  • Hi Kev,

    Sounds like your Exchange Server cannot correctly determine the ADDS version.

    First of all - please specify your environment:

    1. What Service Pack # and Update Rollup # is installed at your Exchange Server 2010?
    2. Windows Server 2012 or 2012 R2 is the Domain Controller?

    Exchange Server 2010 must be minimum SP2 to support Windows Server 2012 DCs, and SP3 UR5 for 2012 R2 Domain Controllers. In case you find your Exchange Server is of a lower version - it's recommended to update it to the latest Service Pack and UR:
