托管WCF服务以通过远程命令生成本地进程

I have need for a work project to run a controller application on PC A, which farms out tasks to PC's B-E. Originally I was planning on using something like psexec or WMI to remotely spawn processes with parameters that then connect back to PC A via WCF, but now I'm leaning towards using WCF as a windows service on B-E and having A connect to them and request that processes be spawned. Does this seem like a good solution? What problems am I likely to encounter and where can I find more information about running WCF services?I have need for a work project to run a control
