Hello,
There is default limit of 5 users when I create new WinRM session configuration and I do not see a property or way to change that. WsMan itself is configured to allow more then that but I did not find a way to change option for WinRM session configuration.
PS WSMan:\localhost\Shell> Get-PSSessionConfiguration -Name JEA | Select MaxConcurrentUsers MaxConcurrentUsers ------------------ 5 WSManConfig: Microsoft.WSMan.Management\WSMan::localhost\Shell Type Name SourceOfValue Value ---- ---- ------------- ----- System.String AllowRemoteShellAccess true System.String IdleTimeout 7200000 System.String MaxConcurrentUsers 30 System.String MaxShellRunTime 2147483647 System.String MaxProcessesPerShell 25 System.String MaxMemoryPerShellMB 1024 System.String MaxShellsPerUser 30
