Then Set Restrict Remote Desktop Services user to a single Remote Desktop Services session to Disabled
If you want to restrict the number of Remote Desktop Services sessions that can be active on a server, Set Limit number of connections to Enabled, and enter the number of connections you want to specify in RD Maximum Connections allowed.
Be aware that if you want or need to allow more than 2 simultaneously sessions, RDS deployment with appropriate RDS CALs installed is necessary.
