WinRM – Remote Execution in PowerShell 2.0

I found that WinRM limits the number of concurrent shells while developing some PowerShell tools that connect around to a bunch servers in parallel. You may get an error like:

“Connecting to remote server failed with the following error message : The WS-Management service cannot process the request. This user is allowed a maximum number of 4 concurrent shells, which has been exceeded. Close existing shells or raise the quota for this user.”

This is how to configure and override the default of 5:

PSH>winrm quickconfig
PSH>winrm get winrm/config
PSH>winrm set winrm/config/winrs `@`{MaxShellsPerUser=`”50`”`}
