SMS 2003 and Desktop Authority each have a place in a well-managed Windows environment. While there is some overlap in features between the products, their core strengths are quite complementary: SMS features a reporting database, desktop remote control, and a robust software distribution and software updates methodology, while ScriptLogic has an intuitive set of no-scripting-required desktop administration features with highly granular Validation Logic.
All organizations with Windows desktops can benefit by implementing ScriptLogic as a healthy first step toward a managed network environment. Larger companies and those who feel that additional features of SMS such as the reporting database, remote control, patch management, and more granular software deployment capabilities are desirable should choose to implement both products.
