Installing Exchange 2016 CU17 - Failed on Mailbox rol: Transport Service RRS feed

  • Question

  • Upgrading from Exchange 2013 to 2016 and when installing Exchange server 2016 CU17 for the first time I keep receiving the following error. I installed Portqry and the port to the domain controller is open. Not sure why this error is occurring? No issues with the Exchange 2013 server CU23. Anyone else run into this issue?

    Error: The following error was generated when "$error.Clear();  install-ExsetdataAtom -AtomName Server -DomainController $RoleDomainController

    " was run: "Microsoft.Exchange.Management.Deployment.ExsetdataException: An error occurred with error code '3221685946' and message 'The RPC server is unavailable.'.    at Microsoft.Exchange.Configuration.Tasks.Task.ThrowTerminatingError(Exception exception, ErrorCategory category, Object target)    at Microsoft.Exchange.Management.Deployment.ManageExsetdataAtom.HandleExsetdataReturnCode(UInt32 scErr)    at Microsoft.Exchange.Management.Deployment.ManageExsetdataAtom.InstallAtom(AtomID atomID)    at Microsoft.Exchange.Management.Deployment.InstallExsetdataAtom.InternalProcessRecord()    at Microsoft.Exchange.Configuration.Tasks.Task.<ProcessRecord>b__91_1()    at Microsoft.Exchange.Configuration.Tasks.Task.InvokeRetryableFunc(String funcName, Action func, Boolean terminatePipelineIfFailed)".

  • The error is stating "RPC server is unavailable", please check if the firewalls are on or off and remove the watermark in the registry and try run the install again.

  • Edward,

    Thank you for the response. We were able to use PortQry to verify the port is open. Found the following in Event Viewer as well.

    Install-ExsetdataAtom, parameters -AtomName "Server" -DomainController "DC1.domain.com".
