By Johan Arwidmark / February 21, 2020

Starting in ConfigMgr 1806, only machines that are online will be returned as a Peer Cache Source. During the process of finding the content for a peer asking for it, ConfigMgr runs the MP_GetSuperPeerContentLocations stored procedure to find the content. However, that stored procedure is a bit complicated to run just for figuring out where […]

By Johan Arwidmark / February 10, 2020

In ConfigMgr, when doing OS Deployment from HTTPS enabled DPs, or via Peer Cache (uses HTTPS too), or via BranchCache (encrypted data + encrypted transfers), you will find that using traditional driver packages, with thousands of small files, is not going as fast as you would like.
