SAS Viya on Windows only supports single-server deployments, so the 'SAS Services Manager' service can be used to start and stop all of the SAS Viya services in the correct sequence:
SAS® Viya® 3.4 Administration: General Servers and Services
If you need to script it you could use a command like:
net start "SAS Services Manager"
or
sc \\hostname start "SAS Services Manager"
The 'VIRK' tool (now called Viya-ARK) which you were using is only available on Linux and not Windows. The equivalent Windows tool SAS® Viya® Deployment Assistant for Windows does not have a facility to manage services.
Many thanks,
