Hi All,

Im am currently trying to install Exchange server 2016 CU6 on a Server 2012R2 machine. The reason i install CU6 is because i want to test the upgrade from CU6 to CU15. For the deployment i used the official Microsoft article: https://docs.microsoft.com/en-us/exchange/plan-and-deploy/plan-and-deploy?view=exchserver-2016

Everything goes wel until step 7. De installation fails with the following error: Unable to set shared config DC.

[03/04/2020 11:05:20.0686] [1] The following 1 error(s) occurred during task execution:
[03/04/2020 11:05:20.0686] [1] 0.  ErrorRecord: Unable to set shared config DC.
[03/04/2020 11:05:20.0686] [1] 0.  ErrorRecord: System.Exception: Unable to set shared config DC.

Are you installing with same name of the current server?
If yes please try changing to a different name.

I suggest you to install new OS with new name and run this command first.
Setup /PrepareAD /IAcceptExchangeServerLicenseTerms

Open in new window

You need Exchange media for this command.

Hi Mas,

There is no current exchange server in the environment i am installing exchange. A few years back there was a exchange server with the same server name. But i've cleaned all old data with adsi edit. Meanwhile, in eventviewer is see more errors:

Process Microsoft.Exchange.Directory.TopologyService.exe (PID=4940). The Exchange computer DC1.contoso.com does not have Audit Security Privilege on the domain controller DC1.Contoso.com

It says the exchange computer "domain controller"  lol ?

Did you try to run?
Setup /PrepareAD /IAcceptExchangeServerLicenseTerms

Open in new window

Did you try after enabling IPv6.
Did you try from a new VM with new OS?

It guides us to add a parameter MinSuitableServer with value 1 in Microsoft.Exchange.Directory.TopologyService.exe.config File.

Besides, sometimes a strict GPO may cause this issue. Here are some examples:

Hi,

My problem is solved. De exchange servers needs to have Manage auditing and security log  rights on the DC. This is defined in the default domain controller policy. Yet, we had another security DC security policy which overruled the default DC policy.

Thanks.!
