Make sure that none of the FLUENT daemons are running on the system. If any are running, you must stop them. Here is the complete list of FLUENT daemons:
fluentlm, icem_cfd, artwork, lmgrd
Things to check for:

Check if you have a Firewall enabled. If so, add lmgrd, Fluentlm, icem_cfd, and artwork and any other daemon needed to run the licensing software.
In the /etc/nsswitch.conf file, modify the hosts and networks lines so that they refer to files before referring to any database. For example:
hosts: nis [NOTFOUND=continue] dns
hosts: files [NOTFOUND=continue] nis dns
This tells the system to search the local database first, then to
search NIS or DNS.
