I have a Windows Server 2016 environment.  
On this server the role Remote Desktop Services is NOT enabled.
On this server the role Remote Access (1 of 3) is installed:  DirectAccesa dn VPN (RAS) (Installed)  

Users have Windows 10 Pro desktop computers in there office.

Some users who are working from home remote (via VPN) into the server to access documents.

Some users who are working from home, establish the VPN connection first, then use Remote Desktop to create a session into there Windows 10 office desktop computer.  It is these users that I am directiing my question to Experts Exchange.

Question:  If I have several  users viewing the webinars from the Windows 10 office desktop computer (via Remote Desktop) "increase network traffic" as opposed to viewing the webinar directly from there own home computer?  
  In other words, the webinar is viewed on the office desktop computer, is the webinar retransmitted to the home computer via the remote destkop session?

Where is the webinar hosted?  Is it on a computer in the office or some other site?

Author

Commented:
The webinar is hosted outside of our office.  For example, the county bar association, or court of appeals, or paralegal training.

Note:  These are "live" webinars.  Where you see the presenter and hear the topic being discussed.

Some are where the judge is hosting the meeting, he can see and speak to me, and I can see and speak to him.

Author

Commented:
But the judge meeting is when I am physically located in the office, sitting at my office desktop computer.

Commented:
99% of the webinars is hosted by someone else, where I "see" and "hear" the presentation on my office desktop computer, but accessing it from my home on a remote desktop connection.

Here is the steps:
I am at home.
I VPN into the offfice server.
I remote desktop connection into my Windows 10 office desktop computer
I open a web browser and navigate to the link of the webinar
I can see and hear the presenter who is doing the webinar "live".
My question is:  The audio and video that I am "viewing" on the office destkop computer, is that information being retransmited again through the remote desktop session, to my home computer?  I hope that makes sense.

Agree the video and audio are being transmitted to your home computer, but have you tried this and is the quality acceptable?  Streaming media generally does not work well with an RDP connection.

Just so I can understand correctly.
The webinar is being transmitted twice:  
Over my office internet, to my windows 10 office desktop computer, and then again over the RDP to my home internet, to my home computer.  
This means there is an increase in network traffic.
Is this correct?

A solution to decrease network traffic, would be to just view the webinar on my home computer over my home internet.  Would this be correct?

If I am only viewing the webinar at home, then the VPN is not used at all for viewing the webinar.  Is that correct?

Yes and qualified yes. (this is known as a split tunnel where all internet traffic bypasses the vpn)

The performance should be far better as well when using your local Internet connection.

Where are you trying to reduce bandwidth? At home or at the office?

For home bandwidth, it probably doesn't make much difference what you do.

If looking at office bandwidth, then using RDP for a webinar is very bad. If you are on VPN, then the whether or not the content first goes to the office depends on how your VPN is setup. Find your public IP on and off VPN by visiting www.ipchicken.com while on VPN and while disconnected from VPN. If the returned public IP is the same both times, then your VPN is configured for split tunnel, which means that your Internet traffic does not go through the office while browsing Internet.

If your public IP changes between VPN and off VPN, then your VPN does a full tunnel.All web browsing traffic will go through the office while on VPN. Full tunnel is more common.
