SYMPTOMS

Because the Web-Based Enterprise Management (WBEM) Query Language is not case sensitive, it causes an unnecessarily large amount of processing overhead on SQL servers that are not case sensitive because all string comparisons are wrapped by a case conversion call.

CAUSE

This problem can occur if the Systems Management Server (SMS) provider does not check the case sensitivity of the SQL server. Although it does not check the case sensitivity of the SQL server, it still provides case conversion, and this can cause the excessive overhead.

RESOLUTION

A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article.

MORE INFORMATION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

Apply this fix to all of the primary sites in the SMS hierarchy. It is necessary to apply the hotfix only to the site servers; you do not need to apply the fix to computers that are running the SMS Administrator console. To install the fix, use one of the following methods.

How to Use the Hotfix Installer

NOTE: You can use this method only on Intel-based computers.
  1. Copy the hotfix folder structure to a share on your network. Q269832.exe is a Microsoft Windows Installer file that updates specific files on your site server.
  2. Log on to your site server by using an account with administrative privileges.
  3. On the site server, quit the SMS Administrator console.
  4. Run Q269832.exe, and then follow the directions in the wizard. You can run the file in Quiet mode by using the /s switch.

How to Manually Install the Hotfix

To determine if the SMS provider is located on the site server or on a remote computer that is running Microsoft SQL Server, view the following registry key on the primary site server:

HKEY_LOCAL_MACHINE\Software\Microsoft\SMS\Setup

Value: Provider Location

NOTE: If the computer that is identified in this registry key is not the local site server, use the installation steps for a remote provider.

Site System with Local Provider

  1. Quit the SMS Administrator console, and then stop all SMS services including the Windows Management service and the SMS_SQL_MONITOR service.
  2. Use Regsvr32.exe to unregister the existing SMS provider file, type regsvr32 /u <sms_root_folder>\bin\<platform>\smsprov.dll at a command prompt, and then press ENTER.
  3. Replace the Smsprov.dll file in the <sms_root_folder>\bin\<platform> folder with the version that you obtained from the hotfix.
  4. Use Regsvr32.exe to register the updated SMS provider file, type regsvr32 <sms_root_folder>\bin\<platform>\smsprov.dll at a command prompt, and then press ENTER.
  5. Restart all SMS services.

Site System with Remote Provider

  1. Quit the SMS Administrator console, and then stop all SMS services.
  2. Use Regsvr32.exe to unregister the existing SMS Provider file, type regsvr32 /u <sms_root_folder>\bin\<platform>\smsprov.dll at a command prompt, and then press ENTER.
  3. Replace the Smsprov.dll file in the <sms_root_folder>\bin\<platform> folder with the version that you obtained from the hotfix.
  4. Use Regsvr32.exe to register the updated SMS provider file, type regsvr32 <sms_root_folder>\bin\<platform>\smsprov.dll at a command prompt, and then press ENTER.
  5. Restart all SMS services.
