We are using the code below to test running a batch file from workflow.  the script builds and appears to run properly, however it never executes.  We actually would like this to run on another server on the network, but simplified to the local LF server when we saw the same results with the network path to the .bat file.  We are seeing no errors or messages when running the script.
