1 TopicNew Installation of Exchange 2016 CU22 fails at step 9
Hello Team, Some Years back, some admin had installed on Exchange 2013 Server and later the desktop's hard drives failed and we lost server. Now again, there was a need for exchange server and I was initially getting the error for Exchange 2013 version. Using ADSIEdit tool I deleted the server, and tried to install Exchange 2016 CU22. I failed again pointing errors for system mailboxes, then I deleted the system mailboxes, federated mailbox & discovery search mailboxes. Re-Prepared all the 3 switches for Schema, AD & AllDomains. Restarted the server and tried the error and it still failed, but this time at step 9. rror: The following error was generated when "$error.Clear(); start-SetupService -ServiceName MSExchangeMailboxAssistants " was run: "Microsoft.Exchange.Configuration.Tasks.ServiceDisabledException: Service 'MSExchangeADTopology' is disabled on this server. ---> System.InvalidOperationException: Cannot start service MSExchangeADTopology on computer '.'. ---> System.ComponentModel.Win32Exception: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it --- End of inner exception stack trace --- at System.ServiceProcess.ServiceController.Start(String[] args) at Microsoft.Exchange.Management.Tasks.ManageSetupService.StartServiceWorker(ServiceController serviceController, String[] serviceParameters) --- End of inner exception stack trace --- at Microsoft.Exchange.Configuration.Tasks.Task.ThrowError(Exception exception, ErrorCategory errorCategory, Object target, String helpUrl) at Microsoft.Exchange.Management.Tasks.ManageSetupService.StartService(ServiceController serviceController, Boolean ignoreServiceStartTimeout, Boolean failIfServiceNotInstalled, Unlimited`1 maximumWaitTime, String[] serviceParameters) at Microsoft.Exchange.Management.Tasks.ManageSetupService.StartService(ServiceController serviceController, Boolean ignoreServiceStartTimeout, Boolean failIfServiceNotInstalled, Unlimited`1 maximumWaitTime, String[] serviceParameters) at Microsoft.Exchange.Management.Tasks.ManageSetupService.StartService(String serviceName, Boolean ignoreServiceStartTimeout, Boolean failIfServiceNotInstalled, Unlimited`1 maximumWaitTime, String[] serviceParameters) at Microsoft.Exchange.Management.Tasks.StartSetupService.InternalProcessRecord() at Microsoft.Exchange.Configuration.Tasks.Task.<ProcessRecord>b__91_1() at Microsoft.Exchange.Configuration.Tasks.Task.InvokeRetryableFunc(String funcName, Action func, Boolean terminatePipelineIfFailed)".3KViews0likes3Comments
