Authority for getting the status of WRKDOMSVR Command

Hello! I need help please.
I have a client who needs to run WRKDOMSVR command in the command line and verify if the DPARs or the Domino Servers are actively running or not.
The issue is, he successfully run the command but unable to get the status of the Domino Servers.
The status of the command is UNKNOWN but when I verify it with my own account, I can see that it is already started.
What do I need to do so he can have access with the WRKDOMSVR command?
