Bug #: 50002379 (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.
If you are a Small Business customer, find additional troubleshooting and learning resources at the Support for Small Business site.
Consider the following scenario. You run a tool that uses Microsoft SQL Server performance counters to collect performance data for an instance of Microsoft SQL Server 2005. For example, you run System Monitor together with SQL Server performance counters. You start the tool before you start the instance of SQL Server. In this scenario, the performance data is not updated after you start the instance of SQL Server. Additionally, the tool displays static performance data instead of displaying the actual real-time performance data from the instance of SQL Server. This problem occurs until you restart the tool.
The tool calls the Sqlctr90.dll file to access the SQL Server performance counters. This DLL works in static mode or in server interaction mode. In static mode, the DLL cannot communicate with SQL Server. The DLL can communicate with SQL Server only in server interaction mode. However, the DLL cannot switch from static mode to server interaction mode after the Sqlctr90.dll file is loaded.
This hotfix is a SQL Server 2005 Service Pack 1-based hotfix. If you have SQL Server 2005 Service Pack 2 installed, do not apply this hotfix. Instead, use the resolution that is described in the following Microsoft Knowledge Base article:
Performance counter data is not updated when you run a tool that uses SQL Server performance counters to collect performance data against an instance of SQL Server 2005
