I've been inspecting the neoloadcmd.exe options here: http://www.neotys.com/documents/doc/neoload/latest/en/
html/#643.htm
And I can't find anything referring to setting or resetting the load generators on the command line. I think I might be having a problem with mine because I am using a different host where I am copying the project files to (yes I have a valid license) when I execute the project and scenario.
I am doing this to integrate with Jenkins.
