[Zope] Zope won't start on Windows NT4

Windows service says " Could not start Zope (Zopey) service on \\MANFRIED error 2140: An internal Windows NT error occured. Ok, for testing I re-install zope into a different directory and it appears to work as base product on port 8080. How do I track down and fix such an errors? Also I can not start the product using the start.bat command.. Hmmmm. Any ideas? Cheers.
