Setup Low Extra Delay Background Transport (LEDBAT) for ConfigMgr

By Johan Arwidmark / July 12, 2018

LEDBAT, or Windows LEDBAT as the Microsoft implementation of it is called, is yet another option to reduce the impact Windows 10, and other software distribution, will have on your network. This feature is currently available on Windows Server, version 1709 or later, and requires Windows 10 v1607 or later on the client side. Hopefully the feature will be backported to Windows Server 2016 too (it’s technically already there, but disabled, and in the need of a bug fix).

Windows 10 and TPM 2.0

By Johan Arwidmark / June 29, 2018

Starting with Windows 10 v1607, OEMs like Dell, HP, Lenovo etc. are required to support TPM 2.0 for new machines certified for Windows 10. Exceptions apply for special purpose commercial systems, as well as custom orders, or machines delivered with a custom image from the customer, but anyway.

Windows 10 Servicing Script – Creating the better In-Place upgrade image

By Johan Arwidmark / June 27, 2018

When doing Windows 10 Servicing, meaning going from one Windows 10 version to the next, it makes absolute sense to do that upgrade using an already updated image. In this post you find a script that does exactly that. This image can obviously also be used for the image you use if upgrading from Windows 7 to Windows 10 (for the few orgs that does).

ConfigMgr Current Branch Setup fails due to TLS 1.2 configuration

By Johan Arwidmark / January 4, 2018

I recently (well yesterday) stumbled across a ConfigMgr Current Branch setup of a new site server failing due to TLS configuration. Turned out that the ConfigMgr 1702 setup (latest baseline as of today) couldn’t install when TLS 1.0 and SSL 3.0 had been removed due to server hardening. The server was Windows Server 2016, and the database SQL was SQL Server 2016 Standard with SP1.

Introducing Peer PXE in ConfigMgr Technical Preview 1712

By Johan Arwidmark / December 17, 2017

Back in ConfigMgr Technical Preview 1706, Microsoft introduced IPv6 PXE, a feature you could enable not only on distribution points running on Windows Server OS, but also on Windows Client OS. Effectively having a Windows client configured as a DP also acting as a PXE server. Microsoft MVP Ronni Pedersen (@ronnipedersen), have a blog post on that:

LEDBAT with ConfigMgr = Pure Love? – By Daniel Olsson

By Johan Arwidmark / November 19, 2017

Here is a new post by guest blogger Daniel Olsson @danielolsson100 covering a quite exciting network feature in Windows 10 and Windows Server 2016. Please note that even though LEDBAT was announced already back in July 18, 2016 by the Windows Networking Team. You need to request assistance to enable LEDBAT from either Microsoft or a Microsoft Partner working with that team. That being said, take it away Daniel (and thanks). / Johan
