I recently upgraded from Zenworks SP to 6.5. All of my stations had desktop
shortcuts that pointed to 'nal.exe' on the server. With the new 6.5 version
of nal.exe, running nal.exe causes an immediate exit without running the
application launcher. Running nalwin32.exe directly gives me an application
launcher window, but I presumably don't get the check/update features of
nal.exe and nalstart.exe. My clients are mostly XP with some older boxes
going back as far as W95. Client software is (alas) a mix of 4.83, 4.9,
4.91 but the behavior is the same on all of them.

What do I need to do to get nal.exe to work again?
