What The Bug ??

Microsoft has released a Security Advisory to address public reports of the Microsoft Windows Server Update Services (WSUS) failing to properly deploy updates within certain environments. Environments that rely on this service for updates may be unable to deploy updates to client systems, some of which may be security related.

This issue prevents the distribution of any updates deployed through Microsoft WSUS 3.0 or Microsoft WSUS 3.0 Service Pack 1 to client systems that have Microsoft Office 2003 installed in their environment.

Currently there is not solution but Microsoft have provided a workaround that require manual removal of duplicate entry in catalog that causing the sync failure. For more details on this issue and the workaround steps, please refer to the Microsoft Security Advisory.
