Unable to configure Entra ID Connect EventID 906 ADSyncBootstrap

Question

Posted at https://answers.microsoft.com/en-us/windowserver/forum/server_devices-servertop_other/unable-to-configure-entra-id-connect-eventid-906/c703eaa1-419d-4849-bb2c-2fac44b96471

AAD Support at Pax8 won't help, says this is a server issue and to open a case with Microsoft Server support. I've tried 3 different version of AAD Sync install on Server 2019. They install fine but during the configuration, it halts at Synchronization Service.

Event log shows

Event 906, ADSyncBootstrap

EnableADSyncBootstrapLocalDBInstance: Error while attempting to enable local db instance. Details: System.InvalidOperationException: LocalDB ShareInstance operation failed.

Server is fully updated and restarted. TLS 1.2 is explicitly enabled.

Have completely uninstalled, restarted, reinstalled each time, same error.

Installed MS SQL Express 2022 just because.

Have ADSync installed on another server but is having errors and it was suggested that it be removed/re-installed. So was going to install in this server then remove from the old one. Maybe I should just roll the dice on the other partially working server and hope it doesn't tank.

Answer 2

Hi @David Sain ,

Did you validate that the uninstall was successful after you rebooted the machine and that there aren't any existing program files from an old installation? I would recommend checking this. You need to perform a reboot between installations.

It sounds like you may have had an older version of AD Connect installed on that server at some point. If this is the case, an in-place upgrade from Version 1 to version 2 is not supported

 

Ideally you should set up a new server for V2 and then export the configuration from V1, which can then be used during setup of new V2 server.

 

After setting up the new server with the settings exported from V1, you need to review pending exports present in the connector space for the Microsoft Entra ID connector.

 

V1 has been out of support for more than 1 year and because of this we will not perform any activity against the V1 server

If the information helped you, please Accept the answer. This will help us and improve searchability for others in the community who may be researching similar questions. Otherwise, let me know if you have further questions.

Answer 3

Well, Microsoft must be aware that this is an issue but has no answer for it. I believe the answer is:
¯\(ツ/¯

Based on everything else I found online, the solution is to build a new server. Customer now has an application server with a single service running on it.

Answer 4

There appears to be no solution other than setup a new server.
