Today I discovered several errors in the event-log of a SharePoint WFE-Server. The error message is in german.

Ausnahme bei der Execute-Methode der Auftragsdefinition 'Microsoft.SharePoint.Search.Administration.SPSearchJobDefinition' (ID 92382b17-cf08-40f0-a2dc-0b7f97fa592f). Weitere Informationen werden unten angezeigt.
 
Die COM-Klassenfactory für die Komponente mit CLSID {629DA12E-9AD5-4FEC-B886-42C5982C5109} konnte aufgrund des folgenden Fehlers nicht abgerufen werden: 80070422.

This error-message was repeated every our. The Windows SharePoint Services Search Service was not functioning correctly. All permission were set correctly in the DCOM-config. Searching google brings am several posts and hints but none of them helped in my case.

Do not disable me, please!

Checking the Timer-Job-Status in central administration simply showed the job was not executed. The search-jobs from the Search Server were okay. So whats the matter? Everything worked before …
After looking inside the services-management for the server I was shocked! The Windows SharePoint Services Search had been deactivated! I don’t know why and how but after setting it to “auto” and starting the service everything runs well again.

Conclusion

Don’t assume anything! Always check the services-management of your service before assuming something else is wrong …
