Netware 4.11 Automated re-boots

I am looking to automate monthly re-boots on my Netware 4.11 servers. I can accomplish this OK on the servers that use ArcServe by running a .NCF batch file after a simple copy job, but some servers are only running NWAGENT. Is there any way to get these servers to run the .ncf batch files on a scheduled basis, unattended?
