Hello,

       Has there been any update to disabling GPU acceleration via GPO? I know there's a mention of the JSON file but I was wondering if there's a registry setting that could be used to set disabling GPU acceleration for Teams? We're running the latest Teams- machine-wide installer. 

If editing the JSON file is the only solution, is there any examples of the modification? Is there any impact to the user when deploying this modified JSON file or PS setting?

Thanks for this fix and all of the time you spent on documentation!!!

This GPO does not solve the problem! You will continue to see mDNS traffic.

This person has created an extensive and helpful solution https://f20.be/blog/mdns

It involves setting a registry setting and mDNS parameters.

I've also disabled all wireless services.

mDNS protocol

GPO settings

I've applied a GPO to disable mDNS. I've double-checked the GPO on the local client. The GPO is correct and applied to Computer settings.

Turn off smart multi-homed name resolution - enabled

Turn off multicast name resolution - enabled

I've also checked the TCP/IP WINS settings disable NetBT so no NetBIOS over TCP/IP. I've disabled this on both network adapters Wired and Wireless. I've removed IPv6 as it's not needed.

When I use Wireshark and ping bob.local I can see MDNS traffic. Why is this protocol still working !!!!

I've used this URL as a reference and have disabled and checked all settings according to this article, even checking the registry!!

I need to fully disable this protocol per our InfoSec Dept.

Which one do I select? Seems ambiguous on the naming convention.
