SYMPTOM:
Users receive the following error when starting Strategy Web:

Error loading projects
No active projects available on server "Intelligence server_name"
CAUSE:
This issue is due to an inconsistency in the Metadata with the Strategy Intelligence Server, such as a project or DB instance being modified or removed and not properly updated in the server definition.
In the event that the DB instance has been modified but the Strategy Intelligence Server definition has not been refreshed properly, the following error message will appear in the DSSErrors.log file from the Strategy Intelligence Server machine:
448:MSIJob::GetErrorsFromMsg(): <0x8004140b><Object with ID 'ED6549284F5ADB3F9B3D91A9F74F3551' and type 29 (DB Instance) is not found in metadata. It may have been deleted.
