Solved: Windows Service does not work but Exe with UI works fine

We have a simple Windows Service that we wrote in C# that is supposed to watch a folder and run a batch file when a new file arrives. On two systems (Win XP and Win 2008), the service works fine but on a Windows 2003 server, it does not work. We made an EXE with UI and tested and that works fine. The service shows up under services.msc and you can start and stop it. There are no errors in Event Log but it does not run that batch file.
Any ideas?

I have pasted the code here as well.
