The following configuration will connect to the RDS broker URL, use the specified collection and connect automatically fullscreen. In the past weeks I've run into this issue that VDI RDS Broker configuration didn't connect full screen once logged in.
I am using the WNOS.ini file in combination with MAC address INI to configure my thin-client connecting to a highly available RDS Broker infrastructure (Windows Server 2016 with PaaS Azure SQL database). Also the configuration should bypass the RD Gateway as it enforces Azure MFA two factor authentication. Once you master the WNOS.ini for the ThinOS the magic will happen to almost zero touch configuration
SessionConfig=RDP \ ForceSpan=No \ TSGWenable=No VDIBroker=https://rds.networknet.nl AutoConnectList=* ConnectionBroker=Microsoft RDCollections="RDS-NL" AutoConnect=Yes SignOn=Yes \ DisableGuest=Yes \ DisableEditDomain=Yes Domainlist=NETWORKNET
- RDCollections="*" –> if star specified any RDS collection available to the user will establish a RDP session. I disabled this as it causes multiple sessions to RD hosts
- TSGWenable=No –> Set TSGWenable to No otherwise it uses the RD Gateway role. In my environement I don't want that, only from the Internet.
