From 9f2b333b6fc788ba3a4947892684dbbf13371fef Mon Sep 17 00:00:00 2001 From: Maurice Daly Date: Wed, 17 Nov 2021 08:35:26 +0000 Subject: [PATCH] Restriction Peer Selection Update In the documentation it currently states that peer selection can be configured to "local peer discovery". This setting can only be set via MDM based policies in Windows 11 builds, and therefore clarification is required, as although technically the docs state 20H2 and docs here - https://docs.microsoft.com/en-us/windows/deployment/update/waas-delivery-optimization-reference, state 1803, setting the value via MDM policies in these builds will result in a policy failure. --- windows/deployment/update/waas-delivery-optimization.md | 3 +++ 1 file changed, 3 insertions(+) diff --git a/windows/deployment/update/waas-delivery-optimization.md b/windows/deployment/update/waas-delivery-optimization.md index 4bd4c62a37..f5441af767 100644 --- a/windows/deployment/update/waas-delivery-optimization.md +++ b/windows/deployment/update/waas-delivery-optimization.md @@ -39,6 +39,9 @@ For information about setting up Delivery Optimization, including tips for the b - New peer selection options: Currently the available options include: 0 = NAT, 1 = Subnet mask, and 2 = Local Peer Discovery.
