LEDBAT or Low Extra Delay Background Transfer is a TCP Congestion control mechanism available in Windows Server 2016 and Windows Server 2019. LEDBAT helps to utilize the entire bandwidth (e.g. for SCCM packages or Windows Updates) when the network is free and if some other task (e.g. Application) requires bandwidth, it will give priority for that task.
Today I tried to configure LEDBAT in my SCCM environment. It's just a simple task as ticking a checkbox in Distribution Point properties. But in the background it does not get configured correctly due to incorrect TCP Templates.
