problem remotely starting pcanywhere using netsvc

I have a remote Windows XP site who's PCA program has stopped. I login via remotedesktop to restart the service. I issue the following command:

netsvc awhost32 \\10.10.10.1 /start

The message I get back states "service is pending start on \\10.10.10.1"

.... but a query shows the service did not start. Does anyone know how to make this work. When we support our remote sites we like to "lockout" the local user when we have to do something, thus PCA is a good choice. Trying to talk the local users through restarting the service can be a real problem sometimes... and a reboot is not a good solution, so I need this to work. Does anyone know why this is not working? Possible solution?

thanks
