The problem: I need a startd (worker) to access one of the system variables that is on the local machine (not the one from which I submitted the job). However, the environment variables list is limited, and does not contain the system variables as seen from the control panel->system->environment variables.
From what I understand , the Windows 'user' that condor runs jobs under only sees a very restricted set of system variables by design. In my case I had to set the environment variables I needed manually in a bat file before calling the .exe to do the real work.
