'Allow New Connections' - change logon /enable | /disable | /query

Hi All

Does RDS Server Manager > Collection Name > Host Servers > Allow New Collections effect the traditional TS key on host servers as this command would have traditionally CMD > change logon /enable | /disable | /query  :

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon] 

"WinStationsDisabled"="0" / "1"

Or does it simply inform the RDCB?

Reason I ask is this reg key doesn't appear to change and I'm not sure if it should or something's broken!

Thanks
