Terminalserver Meeting

Hello Community,

we're trying to run our meetings of a terminalserver session (Win Server 2019). We are only using thinclients.

The problem we're facing is that the call is allways lagging. We know that this ist not an optimal solution, but the only way we are able to use it. 
Using the standard RDP Client from MS.

Any solutions you could offer us?

Thanks,

Sean
