I have a RDS installation on windows server 2019 with a RDS Gateway to connect to a RDS 2019 hosts farm.
When I'm using MSTSC (legacy client), or last version of Microsoft RDS Client : https://docs.microsoft.com/en-us/windows-server/remote/remote-desktop-services/clients/windowsdesktop
The copy paste of fileis reaaaaalllyyy slow, even for a 2 mbytes files.
If i'm connecting locally to the RDS host all is fine.
With the classic client from store :
The speed is perfectly fine.
But I don't want to use the Store Client, as it's impossible to deploy it, and it's not a supported version on the long time.
I already tried to disable UDP on my gateway, and on My client
I also tried to disable URCP (Universal Rate Control Protocol)
I can't work with UDP because of layer 7 LoadBalancer in Frontend.
If someone has same experience, I will be grateful !!
Have a nice day.
