Microsoft distributes Microsoft SQL Server 2008 R2 Service Pack 1 (SP1) or Microsoft SQL Server 2012 fixes in one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security updates that were included with the previous SQL Server 2008 R2 Service Pack 1 (SP1) or Microsoft SQL Server 2012 update release.
Symptoms
Consider the following scenario:
-
You enable the Automatically detect settings option in the Connections tab of Windows Internet Explorer on a client computer.
-
You use Microsoft SQL Server Analysis Services 10.0 OLE DB Provider (Msolap100.dll) to access a SSAS instance that is located outside of the local network, and that requires proxy usage over HTTP. For example, you use an Excel spreadsheet that has a pivot table to obtain data from a data source that is outside of the local network.
In this scenario, SQL Server Analysis Services 10.0 OLE DB Provider cannot connect to the data source.
Notes
-
This issue also occurs for Microsoft SQL Server 2005 Analysis Services (SSAS 2005) and Microsoft SQL Server 2008 Analysis Services (SSAS 2008) OLE DB providers.
