Bug #: 50000441 (SQL Hotfix)



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 applying the hotfix package
 * Whether you must restart the computer after you apply the hotfix package
 * Whether the hotfix package is replaced by any other hotfix package
 * Whether you must make any registry changes after you apply the hotfix package
 * The files that are contained in the hotfix package



SYMPTOMS
In Microsoft SQL Server 2005 Analysis Services, you use the InStr function in a calculated member of a Multidimensional Expressions (MDX) query. When you do this, the query runs much slower than you expect.

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 Analysis Services for HTTP access, you must exit 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 because the Msmdredir.dll component of the SQL Server Browser service is updated when you apply this hotfix.

Registry information
You do not have to change the registry.
