Windows 2008 (R2) system state fails due FSCVSSWriter

In a previous post we discussed the Windows 2008 (R2) system state backup failures because of a FSCVSSwriter issue.

Log Name:      Application

Date:          2-11-2009 17:36:17
Event ID:      11003
Task Category: (11)

Description: Microsoft Forefront Protection VSS Writer failed when preparing for backup. Writer instance: FSCVSSWriter Error code: 0x00000000

The workaround in this post was to disable the FSCVSSWriter. With this workaround you will lose the functionality of the Microsoft Forefront Protection VSS Writer.

There is now a Hotfix Rollup 1 for Microsoft Forefront Protection for Exchange available that includes a fix for this issue. http://support.microsoft.com/kb/2181692
