New Exchange 2016 not working like expected
Posted on 2016-10-01
Hi,
We have in a test environment 2 exchange 2016 servers. Both server 2012 R2. We made a clean install of exchange on both of them. The first one works like expected. We can log in to the admin center and configure it as we want. Als we can make a dag and add the first server as a member.
On the other hand, the second server is not acting like expected. We cannot login to the admin center, we get a 500 error (both locally and from another server).
We see the server listed in the servers section when logged in to the admin center on the first server, but when we double click it to see the properties, it says "An error occured while accessing the registry on the remote server".
In the event log of the second server we see event id:
2010: Failed to create OAuth extension authentication handler: 'OpenIdConnect', the following exception was hit: Microsoft.Exchange.Common.GrayException ---> Microsoft.Exchange.Security.Authentication.AdfsConfigurationException: Encryption certificate is absent................
2001: A transient failure has occurred. The problem may resolve itself. Diagnostic information:
Microsoft.Exchange.Data.DataSourceOperationException: Exchange Web Services are not currently available for this request because none of the Client Access Servers in the destination site could process the request. ---> ...................
I'm most bothered by the fact we cant start the admin center on the second server.
We already uninstalled exchange on the second server and re-installed exchange 2016.
Any suggestions are very welcome.
Regards,
Belali
