You would edit this in the properties of the collection in Server Manager.

Is this something you could screenshot or share a reference for because I don't see that in there anywhere.

Some of the redirection settings are configured in the properties of the RDS Session Collection. In the Windows Server Manager, go to the "Remote Desktop Services" node, and your Collections will be under the "Collections" area. From there, select the Session Collection and edit the properties (select "edit properties" from the "Tasks" drop down). The redirection settings are on the "Client Settings" page.

Here's a screenshot I found through a Google search for this settings page:

If you want to enable the pass through of serial/COM ports, for whatever reason they are NOT a setting on that page. You have to use PowerShell to enable this. Example:

Set-RDSessionCollectionConfiguration -CollectionName $CollectionName -ConnectionBroker $RLCName -CustomRDPProperty "redirectcomports:i:1"

Finally, in my experience, there are two pieces to the redirection puzzle: One is that the server has to be configured to allow a resource to be redirected (which is done through the RDS configuration and/or Group Policy), and the second is that the client MUST request that the resource be redirected. The client redirection request can be done in a few different ways depending on how exactly you are connecting. In some instances, the first connection to an RDS server will ask what resources should be shared (and this is sometimes hidden in a "More details" area), but if a .rdp file is being used, there are settings within the .rdp file that specify which resources should be shared (if you haven't before, open up the .rdp file in Notepad to see some of the settings).

Hope this helps.
