My good friend Deepak Dhami (aka Dexter), who is an expert in PowerShell and System Center Configuration Manager (SCCM / ConfigMgr) is a frequent contributor for great information and resource in these fields. He conducts various user groups and workshops in India to help ConfigMgr admins improve their skills. Dexter has provided the links below on his blog and has generously allowed me to share them on mine in order to further share the goodness.

Feel free to follow and reach out to him. He is always happy to help.
