Symantec PcAnywhere host service did not start automatically

I have some machine after reboot the workstation but the Symantec pcAnywhere Host Service did not started automatically.

is anyway I can find out the report to see how many machines out there?

where is registry key I can look into this?

this is the problem I have in our environment that helpdesk people try to help user with pcAnywhere, but the service did not start then pcAnywhere won't work.

Thanks
