BUG #: 413425 (SQLBUDT)



''Microsoft distributes Microsoft SQL Server 2005 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 fix release.''



SUMMARY
This article describes the following about this hotfix release:
 * The issues that are fixed by the hotfix package
 * The prerequisites for installing the hotfix package
 * Whether you must restart the computer after you install the hotfix package
 * Whether the hotfix package is replaced by any other hotfix package
 * Whether you must make any registry changes
 * The files that are contained in the hotfix package



SYMPTOMS
In SQL Server Management Studio, you run a Multidimensional Expressions (MDX) statement to query data from a Microsoft SQL Server 2005 Analysis Services database. When you do this, you receive the following error message:

Internal error: An unexpected exception occurred

This problem occurs when you use a DROP SET statement to remove a named set that was created as a session-scoped named set.



Service pack information
To resolve this problem, obtain the latest service pack for Microsoft SQL Server 2005. For more information, click the following article number to view the article in the Microsoft Knowledge Base:

913089 How to obtain the latest service pack for SQL Server 2005

Prerequisites
To apply this hotfix, you must have Analysis Services installed on the computer.

Restart information
You do not have to restart the computer after you apply this hotfix. However, this hotfix stops and then restarts the Analysis Services service. If you configured the server for HTTP access, you must stop Microsoft Internet Information Services (IIS) and then restart IIS after the installation is complete. If you installed Analysis Services as a named instance, you must stop the SQL Server Browser service. You must do this because the Msmdredir.dll component of the SQL Server Browser service is updated during the installation of this hotfix.

Registry information
You do not have to change the registry after you apply this hotfix.

Hotfix file information
This hotfix contains only those files that are required to correct the issues that this article lists. This hotfix may not contain all the files that you must have to fully update a product to the latest build.

The English version of this hotfix has the file attributes (or later file attributes) that are listed in the following table. The dates and times for these files are listed in Coordinated Universal Time (UTC). When you view the file information, it is converted to local time. To find the difference between UTC and local time, use the Time Zone tab in the Date and Time tool in Control Panel.

SQL Server 2005 Analysis Services, Itanium architecture version
Note Because of file dependencies, the most recent hotfix that contains these files may also contain additional files.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section. This problem was first corrected in Microsoft SQL Server 2005 Service Pack 1.



MORE INFORMATION
When this problem occurs, the server starts a cycle of restarting and throwing access violations until the service is manually stopped and restarted.
