failed to access the metabase, error code is 80070422 (The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.).

Hello, We will need a bit more info on this one, like the version of server, a little bit on the environement etc. From the looks of it I would say that this has to do with the system attendant not starting on a server. As a first action plan please make sure that all of the below services are started on the server: IIS Admin HTTP SSL SMTP WWW If all of them are started, try to restart them and then try again to start the SA. Also make sure that if you have a file level antivirus you have setup up correctly the Exchange exclusions ( i.e it should not scan the metabase file for IIS, among others) Hope it helps, Mihai

As Mihaiss mentioned, you need to provide more information.
