I have developed a VI in LabVIEW 8.6 that uses WinRAR command-line tools (passed into the System Exec.vi) to archive data that is held on 5 different networked computers, and stores the resulting .rar files on a server. The VI's executable runs perfectly on my development computer (running WinXP). The data from each of the 5 machines is archived and the .rar files are stored on the server. However, when I move the executable to the server where the .rar files will be stored, and run the executable, the command window flashes on the screen as if the WinRAR commands are being executed, but no data is archived onto the server. No errors are passed out of the System Exec.vi. The Server's OS is Windows Server 2012, and I have placed the Rar and UnRAR .exe's in the system32 folder on the server. The server's firewall is disabled, and it is able to explore to the locations of the data to be arhived. The server is logged in as a domain administrator account.
