Unable to mount database RRS feed

  • Question

  • I have a brand new standalone Exchange server 2010 consolidated roles.  Also 1 DC.  Very simple setup (Lab).  After Exchange finished installing, the default database is not mounted.  Then I created a new DB and it wouldn't mount.   I thought I have to wait for replication... waited for DAYS, still don't mount.

    [PS] C:\Windows\system32>Get-MailboxDatabase

    Name                           Server          Recovery        ReplicationType
    ----                           ------          --------        ---------------
    Mailbox Database 0912309164    NEXUSEXCH2010   False           None
    mbx1                           NEXUSEXCH2010   False           None

    [PS] C:\Windows\system32>Mount-Database mbx1
    Couldn't mount the database that you specified. Specified database: mbx1; Error code: An Active Manager operation faile
    d. Error The Microsoft Exchange Replication service may not be running on server NEXUSEXCH2010.nexus13.local. Specific
    RPC error message: Error 0x6d9 (There are no more endpoints available from the endpoint mapper) from cli_MountDatabase3
        + CategoryInfo          : InvalidOperation: (mbx1:ADObjectId) [Mount-Database], InvalidOperationException
        + FullyQualifiedErrorId : 785BB2,Microsoft.Exchange.Management.SystemConfigurationTasks.MountDatabase
        + PSComputerName        : nexusexch2010.nexus13.local

    I've checked all MSExchange services are running.  Domain Controller is fine.  No idea what else to do?  Pls help

  • Hi There,

    Did you check that all the Exchange services are running ?

  • Sounds like a problem with the replication service even though it is running.  I had a similar problem on a 4 node dag where one of my servers was having a service issue.

    Try running: Test-ReplicationHealth -identity "server name" | fl and see if there are any replication errors.  If so try stopping and restarting the replication service.

  • Did you restart the server after the installation?

    Give it a restart anyway and check that ALL Exchange services are running on the box. Make sure that Exchange box can access the Domain controller.

  • Should I still run this even though its a single server with no DAG?

  • I've restarted so many times... Exchange and the DC are on the same subnet

  • Yes all services are running, tripled checked

  • I ran the test replication health and got this:

    [PS] C:\Windows\system32>Test-ReplicationHealth | select error | fl

    Error : An error occurred while reading the state of the Microsoft Exchange Replication service on server 'NEXUSEXCH201
            0'. Verify that the service is running. Error: Service msexchangerepl was not found on computer '.'.

  • Hi,

    For your question, it might be caused by the value of the ConfigurationDomainController parameter and the value of the PreferredGlobalCatalog parameter are different. Please run Get-ADServerSettings | FL to ensure.
    I find an similar thread about your question, for your reference: https://social.technet.microsoft.com/Forums/exchange/en-US/ee1895f7-cec6-4a37-be8a-4bdd621e8bc4/active-manager-failed-to-mount-database-mailbox-database?forum=exchange2010
