    I found a solution to this problem. The root cause is the new printing interface in certain applications like Chrome, Paint, as well as other major systems that use it. To fix this, you just need to switch to the older printing interface by modifying the registry:

    [HKEY_CURRENT_USER\Software\Microsoft\Print\UnifiedPrintDialog]
    Add a DWORD 32-bit named "PreferLegacyPrintDialog" and set it to 1.

    This will disable the new interface and stop the broadcast packets from being sent.

    I'm still trying to figure out the root issue, but it appears to be tied to Edge/Chrome's new Print wizard when on Win 11 24h2.

    It seems whenever a user prints from either Edge or Chrome and their new Print wizard loads, it does some sort of broadcast printer search that never ends.

    It seems when I kill the service "net stop deviceassociationservice" it ends the udp storm. But then when they print again it starts again.

    I'm not sure what the root of the issue is though.

    We have users that have to print from the browser, and I have tried forcing Chrome/Edge to use the system print service, but I'm getting partial success with even that.

    Also seeing this on a fairly new install of Windows 11 24H2

    I have blocked the outbound traffic to stop the network from becoming congested but this is a bandaid at best.

    Has there been any progress on this, either a cause or any better workarounds/fixes?

    I'm experience the same.

    Is it from the last update of Windows 11 24H2?

    dasHost.exe,"10.0.26100.1882","04-Oct-2024","18:33","166,912"

    I am also having the same issue with both ports 22222 and 10004, what you suggested is simply a workaround and I cannot implement these things in our corporate environment. I am seeing over 350,000 packets in the last ten minutes from one device alone. Can I get assistance in figuring this issue out? It's starting to impact our company network. Thanks
