Error creating a DAG without AAP in Exchange Server 2013 SP1

Share this:

In this post we are going over the error “Some or all identity references could not be translated” or “A server-side administrative operation has failed. ‘GetDagNetworkConfig’failed on the server. Error: The NetworkManager has not yet been initialized. Check the event logs to determine the cause. [Server: xxx”]” when creating a new DAG without AAP in Exchange Server 2013 SP1.


The new capability on Exchange Server 2013 to create DAG that do not rely on Active Directory is great and reduces a lot the complexity to manage and operate the system.

However, in one of my labs I was getting the following error message and I have done the same process without any issues.


So, I thought was a configuration issue and started the regular troubleshooting process: Even Viewer, DAG Tasks (C:ExchangeSetupLogsDagTasks) and RIEN. In the the logs of DagTasks I always got a message similar to this one and nothing else:

Update Progress ‘Successfully update the membership of server ‘TOREX01’ in Active Directory group ‘DAG’.’ 17%


After struggling a lot on the issue I asked the help of Microsoft folks (Thanks Scott Schnool and Jared Van Leeuen) and they pointed me out to the problem: I was using a disjoint namespace and that is an issue on the current release.

To be honest, at first glance I thought I wasn’t using a disjoint name space, because my FQDN was apatricio.local and all DNS was using that same name however my NETBios was PATRICIO instead of APATRICIO which qualified my environment as disjoint name space. Yeah, I know that was a layer 8 issue in the OSI Model  (human error :) ) but lesson learnt and XP+ points for next time.


In Jared’s thread below there is a link, but I would like to point out the link here about Disjoint namespace scenarios:

If you do have a disjoint domain namespace, then you should use solution proposed by Jared Van Leeuen on this thread:


The error described in this post is known issue in the current release (Exchange Server 2013 SP1) and the workaround is to use Jared’s suggestion on the post. If you don’t have a disjoint namespace scenario then the process should work just fine.
