This is a topic I haven’t seen much covered around but is quite important, especially if you’re managing an environment with a lot of clients, regular changes and a lot of collections.According to Technet ( Collections in System Center 2012 Configuration Manager provide a method of managing groups of computers, mobile devices, users, and other resources in your organization.
Project Description SCCM Client Actions Tool or SCCM CAT is a practical and simple HTA application for performing most common day-to-day administrative tasks on System Center Configuration Manager 2007 clients.
The tool allows running actions remotely on one or more computers.
A list of computers can be provided either from a file (XLS, XLSX, CSV, TXT), loaded from SCCM collection or simply entered as a text into a text area.
The main goal for creating this tool was to have something simple that doesn’t have any prerequisites and doesn’t require installation. It’s an alternative to SCCM console and right-click tools because it’s not always possible to install SCCM console everywhere and manage clients in closed environments.
Collections can be used to deploy Software, Operating Systems, Task Sequences or settings to these managed groups.
Basics covered, we all now know what a collection is and what it’s for.;-)Collections have members and members can change, that’s why we need to regularly update our collections.This way we guarantee that collections reflect our environment as accurately as possible.There are four ways collections can get their membership rules updates: When creating a collection through the console then this will be the default setting.A full update for this collection will run every seven days.This will then completely reevaluate the collection memberships.
