I want to shut down or Power Off Citrix Xendesktop.
I tried many sites including Citrix docs but couldn't find anything for shutting down the Xendesktop.
Finally I was able to find the Cmdlet to Power off the XenDesktop.
The command is New-BrokerHostingPowerAction -Action Shutdown -MachineName "$domain_name\$machine_name'.
In above command one needs to supply the domain and machine name to poweroff/shutdown the xendesktop from Powershell.
