I just upgraded from ZEN3.2 to 6.5. Users that log into all servers except 1
are processing nalexpld.exe via log script without a problem. At one
building it won't launch however If I change nalexpld.exe to naldesk.exe the
apps are delivered and I can't tell the difference.

1. Why won't nalexpld.exe launch?

2. What is the difference between nalexpld.exe and naldesk.exe?
