**UPDATE**: KB
940252 supersedes KB 929774. It also fixes some serious memory leaks, bringing the revision up to build 4120.
This update is mainly targeted for Exchange 2007 so that it can do a single VSS-based restoration while running multiple VSS-based backups at the same time, under Windows 2003.
It is also a good way of getting the latest VSS fixes if you want to stay with Windows 2003 SP1 for a while, or you are experiencing VSS related problems with Windows 2003 SP2. I know there are many organizations holding off on SP2 for Windows 2003 due to the
SNP (Scalable Networking Pack) issues.
There will be more fixes to Exchange 2007 in Exchange 2007 SP1 related to this issue too, based on the notes in the KB article.
This build (2868 for x86 SP1 and build 4010 for x86 SP2) is dated in Jan of 2007. The
old VSS update-2 (KB 887827) is dated in 2005. The most recent KB article/build I can find before
KB 929774 is
KB 923628.
You might not realize you are using VSS with Server 2003, but most backup solutions use VSS to do snapshots of Exchange servers, Windows servers and many other types of services, as long as they have the proper VSS plugins.
Backup Exec is good example of a program that takes advantage of VSS when it can, and the same can be said for
Windows Home Server.
As always, I recommend only requesting the hotfix if you are having VSS problems. If so, fill out the
online request form and the hotfix should be sent to you soon after. The website says 8 business hours but I have seen turnaround times of less than 15 minutes.
