A recent update to the Windows Update Agent to version 3.0 has been released. This update can help improve Scan Performance with ITMU (as well as non SMS related scanning and patching activities) and is compatible with the ITMUv3. The Windows Update Agent remains external to SMS yet is a dependency for ITMU.
A key combination to getting the best performance is to not only update your agent but also ensure you have the related MSI hotfix. Both the WUA update and the MSI fix are discussed in the WSUS Teams blog found here!
For SMS and ITMU related references on this please review the following two articles which have been recently updated.
· KB 924148 A Systems Management Server (SMS) 2003 client computer stops responding when you try to perform a software update scan of the Inventory Tool for Microsoft Updates (ITMU) on a computer that is running SMS 2003
· KB 932494 When you use Automatic Updates to scan for updates or to apply updates to applications that use Windows Installer, you experience issues that involve the Svchost.exe process
Note: This update is not of a type which is offered through the ITMU Catalog. As this will not be distributable via ITMU other plans to update your clients with this WUA update will be needed.
