Microsoft has released another security update inventory tool for SMS 2003 called the Extended Security Update Inventory Tool. This inventory tool is intended to detect, download and deploy updates that are not detectable by the SMS Security Update Inventory Tool that relies on the Microsoft baseline Security Analyser. The new ESUIT is built on another new release, the Enterprise Scan Tool.
It looks like the tool will work on SMS 2.0 SP3 and SMS 2003
