In the Windows 2012 RDS farm that we setup, the session collection security settings has the attached by default.
A piece of 3rd party software that we use leverages the RDP connection which is not working. The software vendor wants us to change the "Security Layer" to "RDP Security Layer" instead of the default setting "Negotiate" and want us to uncheck the "Allow connections only from computers running remote desktop with network level authentication".
I am not sure if these settings will cause security issue. Please advise if you see a potential issue.
