SQL Server Analysis Services (SSAS) Connection Properties
Recently I was having some issues getting a new SQL Server Analysis Services (SSAS) cube to process on a new development (dev) server. The error I kept receiving was:
[Analysis Services Execute DDL Task] Error: OLE DB error: OLE DB or ODBC error: Login timeout expired; HYT00; An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.; 08001; SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF]. ; 08001.
After much toying around I was able to determine what was causing this. In my case I had my shared data source connection for my data warehouse using Windows Authentication and the Impersonation Info set to Default. The problem appears to stem from the translation from Windows Authentication to the Impersonation Info option.
To fix this I changed my shared data source connection to use a SQL Server account and left the Impersonation Info option as default. This then must have allowed SSAS to translate the username and password info when doing the impersonation. I could be wrong but it is now working.
If you have any comments on this or a deeper explination please share? If you too are experiencing this issue o I hope this helps!
