LoadGen 2013 DB initialization problem RRS feed

  • Question

  • I am running Exchange Server 2013 SP1 on Windows Server 2012 R2 and trying to get LoadGen 2013 running. 

    I get a failure from LoadGen after recipients are created but prior to initialization phase of DBs. There is this popup: 


    Failed to count users for user group 
    UserGroup1:System.DirctoryServices.DirectoryServicesCOMException 
    (0x8007202B): A referral was returned from the server. 

    at System.DirectoryServices.DirectoryEntry.Bind(Boolean throwlfFail) 
    at System.DirectoryServices.DirectoryEntry.Bind() 
    at System.DirectoryServices.DirectoryEntry.get_AdsObject() 
    at System.DirectoryServices.DirectoryEntry.FindAll(BooleanfindMoreThanOne) 
    at Microsoft.Exchange.Swordfish.GUI.SummaryPage.GetADObjectCount(GlobalSettings settings, String ldapBaseDn, String ldapSearchFilter) 
    at Microsoft.Exchange.Swordfish.GUI.SummaryPage.BackgroundWorker_DoWork(Object sender, DoWorkEventArgs e)

    Note LoadGen is running on the Exchange Server 2013 machine which is also the AD and DNS server for this test case.

  • Hi RDvirtualization,

    Hope you are using the only AD server here, otherwise if you have more it might be due to replication issues.

    Secondly deploying Exchange on AD is not a good idea, which might be the actual problem. To me it appears that Exchange is not able to talk to the AD component properly causing this error.

    Installing Exchange on a domain controller is not recommended:

    *Exchange services may not start correctly when the domain controller is also a global catalog server.

    Looking elsewhere found below:

    "A referral is sent by an AD server when it doesn't have the information requested itself, but know that another server have the info. It usually appears in trust environment where a DC can  refer to a DC in trusted domain."

    Something that LoadGen might be using in the backend:

    "LDAP strings can be less than intuitive. LDAP://DC=primary,DC=secondary,DC=com which worked in most cases. But when trying to connect to its sub-domain with full trust, the string had to change to: LDAP://MyDomainController1.primary.secondary.com"
