For your simple test, is this from a batch script, and or an interactive 
session, or is it just from the command line on a head node?


If your simple test is NOT from an interior node to the cluster, my next 
question is can your compute nodes route out to the flexlm server?

The University has 45 licenses for Fluent 6.3.26 and 30 licenses for an older version 6.0/2?? (not sure which). These licenses reside on a windows server with flexlm running on it. We have floating licenses for many softwares on that machine.
