Anturis Monitoring Agent stops every time server reboots

I've installed the agent on a few Windows 2012 R2 Servers - and even after a fresh install, every time one of these servers reboots, the agent service is stopped upon starting up again. If I try to start the agent service manually, I get an "Error 1069: The service did not start due to a logon failure." I haven't made any changes to the Anturis Agent since installing. Re-installing the agent seems to fix it and start the service again, until the next reboot.
