Microsoft Windows 2003 Post-SP2 Hotfixes

by Jeremy Saunders on May 15, 2008

Why should we apply hotfixes?

Some IT Administrators take the approach that if they are not experiencing the issues/symptoms referred to in the knowledge base article; they shouldn’t be deploying the hotfix. However, from experience we understand that the vendor doesn’t always document all issues addressed, so there also needs to be an understanding of previous releases of the same drivers, etc, in other hotfixes.

The Windows StorPort mini driver (storport.sys) is an interesting case, and makes for a good example of this theory. Functions within it are used by most disk subsystem drivers, such as the LSI SAS and QLogic HBA drivers, just to name two. When referring to Windows 2003 SP2, this has been updated in the following hotfixes:

  • KB932755 contains driver version 5.2.3790.4021
  • KB939315 contains driver version 5.2.3790.4121
  • KB940467 contains driver version 5.2.3790.4133
  • KB941276 contains driver version 5.2.3790.4156
  • KB943295 contains driver version 5.2.3790.4163
  • KB943545 contains driver version 5.2.3790.4173

Furthermore, there have also been quite a few forum posts on the HP and QLogic support forums. So if you just looked at knowledge base article KB943545 and read it at face value, you wouldn’t understand the history behind version 5.2.3790.4173. When you correlate all the information at hand, the actual issues addressed can assist with…

  • Disk subsystem performance
  • Random blue screens
  • Server stops responding
  • Server doesn’t shutdown properly
  • Network freezes

The important point made here is that whilst an environment may not be experiencing any “instability” issues, it certainly addresses underlying performance issues that more often than not you don’t even realise you are experiencing.

How does the package installer manage file versions between hotfixes?

For an understanding on how the package installer manages the file versions, please review a Technet article titled “The Package Installer (Formerly Called Update.exe) for Microsoft Windows Operating Systems and Windows Components.

“…The package installer identifies which files to install and examines the currently installed versions of those files. If the current version is the same as or newer than the version being installed, the package installer does not update the file. In rare cases where the version numbers are identical, but the file hashes are different, the package installer updates the file.”
